iOS Advanced Features

Create Content Reference

let buo = BranchUniversalObject.init(canonicalIdentifier: "content/12345")
buo.title = "My Content Title"
buo.contentDescription = "My Content Description"
buo.imageUrl = "https://lorempixel.com/400/400"
buo.publiclyIndex = true
buo.locallyIndex = true
buo.contentMetadata.customMetadata["key1"] = "value1"
BranchUniversalObject *buo = [[BranchUniversalObject alloc] initWithCanonicalIdentifier:@"content/12345"];
buo.title = @"My Content Title";
buo.contentDescription = @"My Content Description";
buo.imageUrl = @"https://lorempixel.com/400/400";
buo.publiclyIndex = YES;
buo.locallyIndex = YES;
buo.contentMetadata.customMetadata[@"key1"] = @"value1";

공유 시트 없이 다이나믹 링크 만들기

고유한 공유 시트를 구축하고 개별 공유 메시지에 대한 Branch 링크를 생성하거나 다른 사용 사례를 갖고 싶다면 다음 호출을 통해 직접 딥링크(Deep Link)를 생성할 수 있습니다.

[branchUniversalObject getShortUrlWithLinkProperties:linkProperties andCallback:^(NSString *url, NSError *error) {
        if (!error) {
            NSLog(@"got my Branch invite link to share: %@", url);
        }
    }];
branchUniversalObject.getShortUrl(with: linkProperties) { (url, error) in
        if (error == nil) {
            print("Got my Branch link to share: (url)")
        } else {
            print(String(format: "Branch error : %@", error! as CVarArg))
        }
    }

You can find examples of linkProperties above. You would next use the returned link and help the user post it to (in this example) Facebook.

Specifying a shared email subjects

대부분의 공유 옵션에는 제목과 본문이 있는 이메일을 제외하고 하나의 텍스트 스트링만 포함됩니다. 공유 텍스트가 본문에 채워지며 아래와 같이 링크 속성에서 이메일 제목을 지정할 수 있습니다.

BranchLinkProperties *linkProperties = [[BranchLinkProperties alloc] init];
    linkProperties.feature = @"share";
    linkProperties.channel = @"facebook";
    [linkProperties addControlParam:@"$email_subject" withValue:@"Your Awesome Deal"];
let linkProperties: BranchLinkProperties = BranchLinkProperties()
    linkProperties.feature = "share"
    linkProperties.channel = "facebook"
    linkProperties.addControlParam("$email_subject", withValue: "Your Awesome Deal")

Create Link Reference

let lp: BranchLinkProperties = BranchLinkProperties()
lp.channel = "facebook"
lp.feature = "sharing"
lp.campaign = "content 123 launch"
lp.stage = "new user"
lp.tags = ["one", "two", "three"]

lp.addControlParam("$desktop_url", withValue: "http://example.com/desktop")
lp.addControlParam("$ios_url", withValue: "http://example.com/ios")
lp.addControlParam("$ipad_url", withValue: "http://example.com/ios")
lp.addControlParam("$android_url", withValue: "http://example.com/android")
lp.addControlParam("$match_duration", withValue: "2000")

lp.addControlParam("custom_data", withValue: "yes")
lp.addControlParam("look_at", withValue: "this")
lp.addControlParam("nav_to", withValue: "over here")
lp.addControlParam("random", withValue: UUID.init().uuidString)
BranchLinkProperties *lp = [[BranchLinkProperties alloc] init];
lp.feature = @"facebook";
lp.channel = @"sharing";
lp.campaign = @"content 123 launch";
lp.stage = @"new user";
lp.tags = @[@"one", @"two", @"three"];

[lp addControlParam:@"$desktop_url" withValue: @"http://example.com/desktop"];
[lp addControlParam:@"$ios_url" withValue: @"http://example.com/ios"];
[lp addControlParam:@"$ipad_url" withValue: @"http://example.com/ios"];
[lp addControlParam:@"$android_url" withValue: @"http://example.com/android"];
[lp addControlParam:@"$match_duration" withValue: @"2000"];

[lp addControlParam:@"custom_data" withValue: @"yes"];
[lp addControlParam:@"look_at" withValue: @"this"];
[lp addControlParam:@"nav_to" withValue: @"over here"];
[lp addControlParam:@"random" withValue: [[NSUUID UUID] UUIDString]];

Create Deep Link

buo.getShortUrl(with: lp) { url, error in
        print(url ?? "")
    }
[buo getShortUrlWithLinkProperties:lp andCallback:^(NSString* url, NSError* error) {
    if (!error) {
        NSLog(@"@", url);
    }
}];

Share Deep Link

let message = "Check out this link"
buo.showShareSheet(with: lp, andShareText: message, from: self) { (activityType, completed) in
  print(activityType ?? "")
}
buo showShareSheetWithLinkProperties:lp andShareText:@"Super amazing thing I want to share!" fromViewController:self completion:^(NSString* activityType, BOOL completed) {
    NSLog(@"finished presenting");
}];

Share with LPLinkMetadata

  • Create a BranchShareLink instance with a BranchUniversalObject and LinkProperties.
  • Set the BranchShareLink's LPLinkMetadata by using the addLPLinkMetadata() function.
  • Present the BranchShareLink's Share Sheet.
//Initialize a BranchShareLink with a BranchUniversalObject and BranchLinkProperties.
//Then set the BranchShareLink's LPLinkMetadata with a preview title and icon.

let bsl = BranchShareLink(universalObject: buo, linkProperties: lp)
bsl.addLPLinkMetadata("LPLinkMetaData Link Title", icon: iconImg)
bsl.presentActivityViewController(from: self, anchor: nil)
//Initialize a BranchShareLink with a BranchUniversalObject and BranchLinkProperties.
//Then set the BranchShareLink's LPLinkMetadata with a preview title and icon.

BranchShareLink *bsl = [[BranchShareLink alloc] initWithUniversalObject:buo linkProperties:lp];
[bsl addLPLinkMetadata:@"LPLinkMetadata Link Title" icon:iconImg];
[bsl presentActivityViewControllerFromViewController:self anchor:nil];

Read Deep Link

  • Retrieve Branch data from a deep link
  • Best practice to receive data from the listener (to prevent a race condition)
  • Returns deep link properties
// listener (within AppDelegate didFinishLaunchingWithOptions)
Branch.getInstance().initSession(launchOptions: launchOptions) { params, error in
  print(params as? [String: AnyObject] ?? {})
}

// latest
let sessionParams = Branch.getInstance().getLatestReferringParams()

// first
let installParams = Branch.getInstance().getFirstReferringParams()
[[Branch getInstance] initSessionWithLaunchOptions:launchOptions
                        andRegisterDeepLinkHandler:^(NSDictionary * _Nullable params,
                                                     NSError * _Nullable error) {
    if (!error) {
        //Referring params
        NSLog(@"Referring link params %@",params);
    }
}];

// latest
NSDictionary *sessionParams = [[Branch getInstance] getLatestReferringParams];

// first
NSDictionary *installParams =  [[Branch getInstance] getFirstReferringParams];

Options for Implementation

  • Enable in the AppDelegate by calling checkPasteboardOnInstall() before the Branch initialization in didFinishLaunchingWithOptions
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // enable pasteboard check  
    Branch.getInstance().checkPasteboardOnInstall()
    
    // listener for Branch Deep Link data
    Branch.getInstance().initSession(launchOptions: launchOptions) { (params, error) in
        // do stuff with deep link data (nav to page, display content, etc)
        print(params as? [String: AnyObject] ?? {})
    }
  return true
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // enable pasteboard check
        [[Branch getInstance] checkPasteboardOnInstall];

        // listener for Branch Deep Link data
    [[Branch getInstance] initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary * _Nonnull params, NSError * _Nullable error) {
        // do stuff with deep link data (nav to page, display content, etc)
            NSLog(@"%@", params);
    }];
    return YES;
}
  • Enable in the AppDelegate for iOS 15+ Only
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // enable pasteboard check for iOS 15+ only
          if #available(iOS 15.0, *) {
           Branch.getInstance().checkPasteboardOnInstall()
        }
    
    // listener for Branch Deep Link data
    Branch.getInstance().initSession(launchOptions: launchOptions) { (params, error) in
        // do stuff with deep link data (nav to page, display content, etc)
        print(params as? [String: AnyObject] ?? {})
    }
  return true
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // enable pasteboard check for iOS 15+ only
        if (@available(iOS 15.0, *)) {
        [[Branch getInstance] checkPasteboardOnInstall];
    }
    

        // listener for Branch Deep Link data
    [[Branch getInstance] initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary * _Nonnull params, NSError * _Nullable error) {
        // do stuff with deep link data (nav to page, display content, etc)
            NSLog(@"%@", params);
    }];
    return YES;
}
  • Enable in the AppDelegate with check notification
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // enable pasteboard check  
          if #available(iOS 15.0, *) {
           Branch.getInstance().checkPasteboardOnInstall()
        }
  
    // check if pasteboard toast will show
    if Branch.getInstance().willShowPasteboardToast(){
        // devlopers can notify the user of what just occurred here if they choose
        
    }
  
    // listener for Branch Deep Link data
    Branch.getInstance().initSession(launchOptions: launchOptions) { (params, error) in
        // do stuff with deep link data (nav to page, display content, etc)
        print(params as? [String: AnyObject] ?? {})
    }
  return true
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // enable pasteboard check
        if (@available(iOS 15.0, *)) {
        [[Branch getInstance] checkPasteboardOnInstall];
    }
  
    // check if pasteboard toast will show
    if ([[Branch getInstance] willShowPasteboardToast]) {
        // developers can notify the user of what just occurrred here if they choose
        
    }

        // listener for Branch Deep Link data
    [[Branch getInstance] initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary * _Nonnull params, NSError * _Nullable error) {
        // do stuff with deep link data (nav to page, display content, etc)
            NSLog(@"%@", params);
    }];
    return YES;
}

iOS 16 UIPasteControl Support

With iOS 16, Apple introduced an automatic modal prompt to request permissions from the user whenever the pasteboard is accessed for an item. UIPasteControl is an alternative for you to create your own prompt requesting access to the pasteboard.

This approach does not interfere with the Branch initialization and Branch will treat the paste action as if it was an in-app deep link.

❗️

Backwards Compatibility

Do not call both checkPasteboardOnInstall and passPasteItemProviders or use BranchPasteControl without properly version checking, as checkPasteboardOnInstall will be called on iOS 16+ as well.

if #available(iOS 16, *) {
    Branch.getInstance().passPaste(itemProviders)
}
if (@available(iOS 16.0, *)) {
   [[Branch getInstance] passPasteItemProviders:itemProviders]
}
// Setup UIPasteControl Configuration
let pcConfig = UIPasteControl.Configuration()
pcConfig.baseBackgroundColor = UIColor.blue
pcConfig.displayMode = UIPasteControl.DisplayMode.iconOnly

// Create Frame and button
let frameDimension = CGRect(x: 0, y: 0, width: 40, height: 40)
let bc = BranchPasteControl(frame: frameDimension, configuration: pcConfig)

// Add BranchPasteControl button to superview
view.addSubview(bc)
// Setup UIPasteControlConfiguration
UIPasteControlConfiguration *pcConfig = [[UIPasteControlConfiguration alloc] init];
pcConfig.baseBackgroundColor = UIColor.blueColor;
pcConfig.displayMode = UIPasteControlDisplayModeIconOnly;

// Create Frame and button
CGRect frameDimension = CGRectMake(0, 0, 120.0, 30.0);
BranchPasteControl *bc = [[BranchPasteControl alloc] initWithFrame:frameDimension AndConfiguration:pcConfig];

// Add BranchPasteControl button to superview
[view addSubview:bc];

📘

BranchPasteControl & UIPasteControl Tips

BranchPasteControl.frame & UIPasteControl.frame
Based on our testing there are undeclared restrictions as to the width and height for UIPasteControl corresponding to the declared DisplayMode. We found the minimum height for all display modes is 40, while the minimum width are as followed:

  • .iconOnly: 40
  • .labelOnly: 60
  • .iconAndLabel: 80

The BranchPasteControl only accepts UTType.url as an acceptable type identifier for its UIPasteConfiguration, if the main purpose is to support NativeLink, we strongly suggest to do the same.

If utilizing your own UIPasteControl, we recommend to clear the pasteboard after accessing it.

When there is not an acceptable type copied to the Pasteboard, the BranchPasteControl and UIPasteControl UI will be greyed out.

Create QR Code

  • Create a BranchQRCode object and set the properties
  • Create a BranchUniversalObject and BranchLinkProperties
  • Use getQRCodeAsImage() or getQRCodeAsData() to create a QR code
  • Use showShareSheetWithQRCodeFromViewController() to create a QR code and share it via the Share Sheet.
let qrCode = BranchQRCode()
qrCode.codeColor = UIColor.white
qrCode.backgroundColor = UIColor.blue
qrCode.centerLogo = "https://cdn.branch.io/branch-assets/1598575682753-og_image.png"
qrCode.width = 1024
qrCode.margin = 1
qrCode.imageFormat = .JPEG

let buo = BranchUniversalObject()
let lp = BranchLinkProperties()

qrCode.getAsImage(buo, linkProperties: lp) { qrCodeImage, error in
    //Do something with your QR code here...
}

//Or display the QR code directly in a share sheet
qrCode.showShareSheetWithQRCode(from: self, anchor: nil, universalObject: buo, linkProperties: lp) { error in
    //Showing a share sheet with the QR code
}
BranchQRCode *qrCode = [BranchQRCode new];
qrCode.codeColor = [[UIColor new] initWithRed:0.1 green:0.8392 blue:0.8667 alpha:1.0];
qrCode.backgroundColor = [UIColor whiteColor];
qrCode.width = @700;
qrCode.margin = @1;
qrCode.centerLogo = @"https://cdn.branch.io/branch-assets/1598575682753-og_image.png";
qrCode.imageFormat = BranchQRCodeImageFormatPNG;
    
BranchUniversalObject *buo = [BranchUniversalObject new];
BranchLinkProperties *lp = [BranchLinkProperties new];

[qrCode getQRCodeAsImage:buo linkProperties:lp completion:^(UIImage * _Nonnull qrCode, NSError * _Nonnull error) {
    //Do something with the QR code here...
}];

//Or display the QR code directly in a share sheet
[qrCode showShareSheetWithQRCodeFromViewController:self anchor:nil universalObject:buo linkProperties:lp completion:^(NSError * _Nullable error) {
    //Showing a share sheet with the QR code
}];

Navigate to Content

Handle Branch Links when using Branch & Firebase SDK

There is a known issue with Firebase where it will call the following Instance Methods:

To account for this, you must check the link first to determine if it should be handled by the Branch SDK:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
  //check for link_click_id
  if url.absoluteString.contains("link_click_id") == true{
    return Branch.getInstance().application(app, open: url, options: options)
  }
}

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
  //check for app.link or appropriate Branch custom domain
  if userActivity.webpageURL?.absoluteString.contains("app.link"){
    return Branch.getInstance().continue(userActivity)
  }
}
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
  if ([url.absoluteString containsString:@"link_click_id"])  {
    return [[Branch getInstance] application:app openURL:url options:options];
  }
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler {
  if ([userActivity.webpageURL.absoluteString containsString:@"app.link"]) {
    return [[Branch getInstance] continueUserActivity:userActivity];
  }
}

Handle Push Notifications

  • Allows you to track Branch deep links in your push notifications
  • Include the Branch push notification handler in Initialize Branch
  • Add a Branch deep link in your push notification payload
    • Replace https://example.app.link/u3fzDwyyjF with your deep link
{
  "aps": {
    "alert": "Push notification with a Branch deep link",
    "badge": "1"
  },
  "branch": "https://example.app.link/u3fzDwyyjF"
}

Handle Links in Your Own App

  • Allows you to deep link into your own from your app itself
Branch.getInstance().handleDeepLink(withNewSession: URL(string: "https://example.app.link/u3fzDwyyjF"))
[[Branch getInstance] handleDeepLinkWithNewSession:[NSURL URLWithString:@"https://example.app.link/u3fzDwyyjF"]];

❗️

Handling a new deep link in your app

Handling a new deep link in your app will clear the current session data and a new referred "open" will be attributed.

Delay Branch Initialization

Delay the Branch initialization on Installs in order to request tracking permission from the user.

  1. Create a boolean flag to represent an Install session and set it to true (e.g. firstOpen)
  2. Before the Branch init in didFinishLaunchingWithOptions
    a. if false continue with Branch SDK init
    b. if true:
    i. Persist launchOptions throughout onboarding flow or store locally when firstOpen is true
    ii. Continue with onboarding flow
  3. After determining User's tracking preference
    a. Set tracking in Branch SDK per User's preference
    b. Initilialize the Branch SDK utilizing the persisted launchOptions
  4. Set Install boolean (firstOpen) to false

Enable 100% Matching

To enable 100% Matching on iOS through Installs, please utilize our NativeLink™ feature.

Enable / Disable User Tracking

If you need to comply with a user's request to not be tracked for GDPR purposes, or otherwise determine that a user should not be tracked, utilize this field to prevent Branch from sending network requests. This setting can also be enabled across all users for a particular link, or across your Branch links.

Branch.setTrackingDisabled(true)
[Branch setTrackingDisabled:YES];

You can choose to call this throughout the lifecycle of the app. Once called, network requests will not be sent from the SDKs. Link generation will continue to work, but will not contain identifying information about the user. In addition, deep linking will continue to work, but will not track analytics for the user.

Share to Email Options

  • Change the way your deep links behave when shared to email
  • Needs a Share deep link
lp.addControlParam("$email_subject", withValue: "Your Awesome Deal")
lp.addControlParam("$email_html_header", withValue: "<style>your awesome CSS</style>\nOr Dear Friend,")
lp.addControlParam("$email_html_footer", withValue: "Thanks!")
lp.addControlParam("$email_html_link_text", withValue: "Tap here")
[lp addControlParam:@"$email_subject" withValue:@"This one weird trick."];
[lp addControlParam:@"$email_html_header" withValue:@"<style>your awesome CSS</style>\nOr Dear Friend,"];
[lp addControlParam:@"$email_html_footer" withValue:@"Thanks!"];
[lp addControlParam:@"$email_html_link_text" withValue:@"Tap here"];

Share Message Dynamically

  • Change the message you share based on the source the users chooses
  • Needs a Share deep link
// import delegate
class ViewController: UITableViewController, BranchShareLinkDelegate

func branchShareLinkWillShare(_ shareLink: BranchShareLink) {
  // choose shareSheet.activityType
  shareLink.shareText = "\(shareLink.linkProperties.channel)"
}
// import delegate
@interface ViewController () <BranchShareLinkDelegate>

  - (void) branchShareLinkWillShare:(BranchShareLink*)shareLink {
  // choose shareSheet.activityType
  shareLink.shareText = [NSString stringWithFormat:@"@%", shareLink.linkProperties.channel];
}

continueUserActivity에 YES를 반환합니다.

When users enter your app via a Universal Link, we check to see to see if the link URL contains app.link. If so, Branch.getInstance().continue(userActivity) will return YES. If not, Branch.getInstance().continue(userActivity) will return NO. This allows us to explicitly confirm the incoming link is from Branch without making a server call.

For most implementations this will never be an issue, since your deep links will be routed correctly either way. However, if you use a custom link domain and you rely on Branch.getInstance().continue(userActivity) to return YES for every incoming Branch-generated Universal Link, you can inform the Branch SDK by following these steps:

  1. In your Info.plist file, create a new key called branch_universal_link_domains.
  2. 커스텀 도메인(들)을 스트링으로 추가합니다. imageimage
  3. 파일을 저장하십시오.

📘

여러 커스텀 도메인

If you have an unusual situation with multiple custom link domains, you may also configure branch_universal_link_domains as an array of strings. imageimage

웹 전용 콘텐츠에 대한 링크 처리

🚧

범용 이메일 만

If you have links to content that exists only on the web and not in the app (for example, a temporary marketing webpage that isn't in the app), then this code snippet will ensure all links that have not had the deep linking script applied will open in a browser.

You should add this code snippet inside the deep link handler code block.

📘

Note

This uses query parameter $web_only=true. This should match the query parameter on the web URL you enter in the email.

[branch initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary *params, NSError *error) {
  // params are the deep linked params associated with the link that the user clicked before showing up.
  if (params[@"$3p"] && params[@"$web_only"]) {
            NSURL *url = [NSURL URLWithString:params[@"$original_url"]];
            if (url) {
                [application openURL:url]; // check to make sure your existing deep linking logic, if any, is not executed, perhaps by returning early
            }

                        application.openURL(url)
                    }

Universal Links with Web-Only Content

Web-only Branch links that redirect to a site that hosts its own AASA file where Universal Links (UL) is enabled will cause unexpected behavior. Since Branch does not have a way to bypass UL (via JavaScript, delays, etc.), you must add a query param exclusion in the AASA file to persist web-only behavior when redirecting to a website. This only applies if you are trying to redirect via $web_only=true to their own website.

Add the following filter to the AASA File:

{
  "/": "*",
  "?": { "$web_only": "true" },
  "exclude": true,
  "comment": "Matches any URL which has a query item with name '$web_only' and a value of exactly true"
}

Now if $web_only=true is appended to the final fallback URL / redirect, iOS will not attempt to launch the App even if it is installed. ex. https://myhomepage.com/?$web_only=true
This link with the query parameter can now be used as the fallback of a web-only Branch link and persist the behavior all the way to myhomepage.com.

Set initialization metadata

🚧

Data Integration Only

If you are using a 3rd Party Data Integration Partner that requires setting certain identifiers before initializing the Branch SDK, you should add this code snippet:

//Inside *didFinishLaunchingWithOptions*
[[Branch getInstance] setRequestMetadataKey:@"{ANALYTICS_ID}" value: […]];

Replace {ANALYTICS_ID} with your Data Integration Partner's key.

App Clips

👍

App Clip Analytics

We will automatically attribute App Clip touches (like a QR Code scan) and sessions.
Touch:

  • Event Name: Click
  • last_attributed_touch_data_tilde_customer_placement: APP_CLIP
  • last_attributed_touch_data_tilde_creative_name: Set as $app_clip_id value if it is present in the App Clip link.

Session:

  • Event Name: Install/Open
  • user_data_environment: APP_CLIP
  • last_attributed_touch_data_tilde_creative_name: Set as $app_clip_id value if it is present.

An App Clip is a lightweight version of your app that offers users some of its functionality when and where they need it.

Follow Apple's developer documentation on creating an App Clip with Xcode

📘

Important to note

  • The Associated Domains entitlement has a new appclips type, which is required if you’re implementing app clips.
    • The AASA file must be updated to support app clips; via a Branch database update.
      • Please Submit a Ticket to make this request. Make sure to include your App Clip bundle ID and team ID in your request.

The Branch iOS SDK must be integrated into an App Clip in the same way as the Full App; with the following caveats:

  • You do not need the applinks setting in the App Clip's Associated Domains entitlement.
  • Cocoapods does not install the Branch SDK into your App Clip.

How to Persist App Clip Install Data to Subsequent Full App Install

  1. Add an App Groups entitlement.
  2. Choose a group will be used to share data between the App Clip and subsequent Full App install.
25602560
  1. In both your Full App and App Clip, inform the Branch SDK of the App Group name prior to calling initSession. See Apple's developer doc for more information.
[[Branch getInstance] setAppClipAppGroup:@"group.io.branch"];
Branch.getInstance().setAppClipAppGroup("group.io.branch")

Branch Links as App Clip Invocation URLs

You can configure Branch links to be associated with App Clips. When creating a link, you specify which App Clip the Branch link should open. You do this via a Branch link parameter called $app_clip_id.

For example, let's say you have two App Clips, one for Stores and one for Products.

On the iTunesConnect Dashboard, you'd register the following two as advanced App Clip Experiences:

  • your.app.link/ac/s/* -- for Store links
  • your.app.link/ac/p/* -- for Product links

Then when creating a Branch link, you set $app_clip_id: s, as seen below:

14681468

Then Branch will automatically create a link with the App Clip ID as part of the path: https://your.app.link/ac/s/QfJ2H7c7jcb.

Additionally, you can specify an alias for these links. If you set $app_clip_url = s and alias to 12345, you'll get the following link: https://your.app.link/ac/s/12345. This would be a great way to create a link to Store with ID 12345!

📘

Note

https://your.app.link/ac/s/12345 returns the same payload as https://your.app.link/12345. The path elements are only to ease registering App Clip experiences.

🚧

App Clip Code invocation URLs have a short character length limit

Unlike most App Clips, App Clip Code has a short URL limit. The length limit varies, but is about 35 characters. It is possible your Branch Link will be too long to be used in this situation. Use the shortest placement identifier possible to increase the odds your generated link will be short enough. We recommend specifying a short $app_clip_id and a short alias.

https://developer.apple.com/documentation/app_clips/creating_app_clip_codes

Invoking App Clips on iOS Channels

Once you have registered your Branch App Clip with Apple, Apple allows you to invoke App Clips on a few channels. Here's an example: https://branchster.app.link/6ZfIMUrDzbb#appclip

iMessage

200200

Branch Links will automatically register and display your App Clip CTA on iMessage by default if they are registered as App Clip Invocation URLs.

Safari Banner

200200

You can also display an App Clip banner on your website yourself. In order to do this, you need to add the standard Apple meta tag to your website:

<meta name="apple-itunes-app" content="app-id=myAppStoreID, app-clip-bundle-id=appClipBundleID>

If you want to display the banner on a Branch Deepview, add it to the HTML code in the Branch dashboard Deepview Manager.

For more information, please refer to Apple's documentation.

Include Apple's ATTrackingManager

🚧

Requires the inclusion of AdSupport Framework

In order for the ATTrackingManager to function, you must also ensure you've added the AdSupport framework in your iOS SDK implementation.

By default, the Branch SDK does not include the ATTrackingManager which is required by Apple if you want to collect the IDFA for attribution purposes.

Learn more about Apple's App Transparency Tracking Manager.

If you wish to use the IDFA, you will need to display the ATTrackingManager prompt at an appropriate time in your app flow. This sample code demonstrates displaying the prompt and logging the IDFA.

func requestIDFAPermission() {
        if #available(iOS 14, *) {
            DispatchQueue.main.async {
                ATTrackingManager.requestTrackingAuthorization { (status) in
                    if (status == .authorized) {
                        let idfa = ASIdentifierManager.shared().advertisingIdentifier
                        print("IDFA: " + idfa.uuidString)
                    } else {
                        print("Failed to get IDFA")
                    }
                }
            }
        }
    }
- (void)requestIDFAPermission {
    if (@available(iOS 14.0, *)) {
        dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
        dispatch_async(dispatch_get_main_queue(), ^{
            [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
                if (status == ATTrackingManagerAuthorizationStatusAuthorized) {
                    NSUUID *idfa = [[ASIdentifierManager sharedManager] advertisingIdentifier];
                    NSLog(@"IDFA: %@", idfa);
                } else {
                    NSLog(@"Failed to get IDFA permission");
                }
                dispatch_semaphore_signal(semaphore);
            }];
        });
        dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
    }
}

Starting from Branch iOS SDK 1.39.1, the SDK will see the authorization status if it is granted by the end-user. There is no additional work on your end to inform the Branch SDK.

On older versions of the SDK, the server infers the authorization status by the presence of the IDFA. Again there is no additional work on your end to inform the Branch SDK.

Set Hashed Information for Facebook Advanced Matching

You can pass additional hashed information to the SDK before initSession() for Facebook Advanced Matching.
