Where can I put this code?

[waheedshabeer]

• (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions { ... // Define UNUserNotificationCenter UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; center.delegate = self;

  return YES; }

//Called when a notification is delivered to a foreground app. -(void)userNotificationCenter:(UNUserNotificationCenter )center willPresentNotification:(UNNotification )notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler { completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge); }

didFinishLaunchingWithOptions already exists in your AppDelegate.m file, so add the

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;

lines before the return statement and for the other method just make sure its under @implementation AppDelegate
