Answer 1

You can try

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
  if([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive ) {
        completionHandler(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
   else {
        completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
   }

}
