App Tracking Transparency

Starting in iOS 14.5, IDFA will be unavailable until an app calls the App Tracking Transparency framework to present the app-tracking authorization request to the end-user. If an app does not present this request, the IDFA will automatically be zeroed out, which may lead to a significant loss in ad revenue.

To display the App Tracking Transparency authorization request for accessing the IDFA, update your Info.plist to add the NSUserTrackingUsageDescription key with a custom message describing the usage.

<key>NSUserTrackingUsageDescription</key>
<string>This identifier will be used to deliver personalized ads to you.</string>

And AppTrackingTransparency.framework to your project.

Stack Consent Manager

Appodeal SDK provides a simple way to integrate App Tracking Transparency. It will obtain request status and show ATT request if needed using Stack Consent Manager framework. You need to enable corresponding message in your AdMob account. See this guide for more details.

Consent Manager integration remains the same as in the GDPR/CCPA section.

Consent Manager will show ATT request only for users under iOS 14.5 or higher, you may want to add some notes in App Review Information section of the app version page in App Store Connect. For example, it can be something like: App Tracking Transparency request is only available for users under iOS 14.5 or higher. This step may be needed because Apple can reject builds that contain AppTrackingTransparency.framework, but do not display ATT requests at app launch.

Manually

Call requestTrackingAuthorizationWithCompletionHandler: to present the App Tracking Transparency authorization request alert. Call this method at the application launch event. We recommend initializing Appodeal SDK in the completion block.

Swift

import AppTrackingTransparency
import AdSupport

class AppDelegate : UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        ATTrackingManager.requestTrackingAuthorization() { status in
            // Tracking authorization completed. Initialise Appodeal here.
        }
        return true
    }
}

Objective-C

#import <AppTrackingTransparency/AppTrackingTransparency.h>
#import <AdSupport/AdSupport.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
        // Tracking authorization completed. Initialise Appodeal here.
    }];
    return YES;
}
