title: Local Push notification not working in Xamarin iOS
body: <p>I am using Xamarin.forms and implemented Local push notification for iOS. It is working successfully when I am debugging the app through visual studio even when the app is minimized, the app can able to receive the notification. But while running the app directly without debugging through visual studio, the app is not able to display the notification. Kindly guide me on this. </p>
  
  <p>Then I also tried by releasing the app to the app store but experienced the same, the app is not able to receive the notification it not even in foreground mode.</p>
  
  <p>I already have selected the "Background fetch" property under Background Modes in Info.plist.
  I have also added below the line in my FinishedLaunching method</p>
  
  <pre><code>UIApplication.SharedApplication.SetMinimumBackgroundFetchInterval(UIApplication.BackgroundFetchIntervalMinimum);
  </code></pre>
  
  <p>Entire Implementation of code is as below</p>
  
  <pre><code>   public override bool FinishedLaunching(UIApplication app, NSDictionary options)
      {
          try
          {
              UIApplication.SharedApplication.SetMinimumBackgroundFetchInterval(UIApplication.BackgroundFetchIntervalMinimum);
  
              try
              {                    
  
                  if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
                  {
                      UNUserNotificationCenter.Current.RequestAuthorization(UNAuthorizationOptions.Alert |
                          UNAuthorizationOptions.Sound |
                          UNAuthorizationOptions.Sound,
                          (granted, error) =&gt;
                          {
                              if (granted)
                              {
                                  InvokeOnMainThread(UIApplication.SharedApplication.RegisterForRemoteNotifications);                                    
                              }
                          });
                  }
                  else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
                  {
                      var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
                      UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
                      new NSSet());
  
                      UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
                      UIApplication.SharedApplication.RegisterForRemoteNotifications();
                  }
                  else
                  {
                      UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
                      UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
                  }
  
                  bool IsRegistered = UIApplication.SharedApplication.IsRegisteredForRemoteNotifications;
              }
              catch (Exception ex)
              {
                  UIAlertView avAlert = new UIAlertView("FinishedLaunching Push Notification Exception", ex.Message, null, "OK", null);
                  avAlert.Show();
              }
  
              UNUserNotificationCenter.Current.Delegate = new UserNotificationCenterDelegate();
  
              LoadApplication(new MessengerClient.App());
  
          }
          catch (Exception ex)
          {
              NativeHelper.SendUnhandledException(ex, NativeHelper.iOS + ": FinishedLaunching");
          }
          return base.FinishedLaunching(app, options);
      }
  
      public override void ReceivedLocalNotification(UIApplication application, UILocalNotification notification)
      {  
          /// reset our badge
          UIApplication.SharedApplication.ApplicationIconBadgeNumber = 0;
  
          /// Cancel/clear all Local notifications fronm the tray.
          UIApplication.SharedApplication.CancelLocalNotification(notification);
  
          /// Cancel/clear all notifications fronm the tray.
          UIApplication.SharedApplication.CancelAllLocalNotifications();
      }
  </code></pre>
  
  <p>code for displaying the notification is as below.</p>
  
  <pre><code>UILocalNotification notification = new UILocalNotification();
          notification.FireDate = NSDate.FromTimeIntervalSinceNow(1);
          notification.AlertAction = title;
          notification.AlertBody = content;
          notification.AlertTitle = title;
          notification.SoundName = UILocalNotification.DefaultSoundName;
          notification.ApplicationIconBadgeNumber = 1;            
          UIApplication.SharedApplication.ScheduleLocalNotification(notification);
  </code></pre>
  
  <p>I know this is the repeat question but, I tried all the workaround but didn't work for me.</p>
