-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(@"User Info = %@",notification.request.content.userInfo);
completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound);
