Handling user notifications on iOS 10

Question

I have troubles determining when the user taps on a user push notification on iOS 10.

So far, I have been using the -[UIApplicationDelegate application:didRece

Answer 1

We were facing the same problem here and we were only able to solve this problem on iOS 10 GM release by using the code on the answer given here: https://forums.developer.apple.com/thread/54332

     - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {  

           NSOperatingSystemVersion version = [[NSProcessInfo processInfo] operatingSystemVersion];
           if (version.majorVersion == 10 && version.minorVersion == 0) {
              [self application: application 
   didReceiveRemoteNotification: userInfo    
         fetchCompletionHandler: ^(UIBackgroundFetchResult result) { 

            }];
       }

With this fix our code started working again both on iOS 9 and 10.

We also had to change the way we handle application state behavior (UIApplicationStateActive, UIApplicationStateInactive and UIApplicationStateBackground) on push notifications, as it seems it also changed on iOS 10

EDIT:

• It seems that application state behavior is back to normal on latest iOS 10 versions.

Swift code for iOS 10:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    if #available(iOS 10.0, *) {
        let center = UNUserNotificationCenter.currentNotificationCenter()
        center.delegate = self
    }

    // ...

    return true
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {

    print(response.notification.request.content.userInfo)        
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {

    print(notification.request.content.userInfo)
}

This has been fixed in iOS 10.1 Beta 1 !!

The -[UIApplicationDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:] is correctly called when the user taps on a notification.
