Detect if application: didReceiveRemoteNotification: fetchCompletionHandler: was called by tapping on a notification in Notification Center

Question

application: didReceiveRemoteNotification: fetchCompletionHandler:

is different from

application: didReceiveRemoteNotification:
         


        

Answer 1

In iOS 10.0+ you can use the method

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler;

to detect when user taps on a system-displayed alert from the NotificationCenter.

If you implement the method above

• - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler; will be called only when a notification is received
• - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler; will be called when user taps on notification
