Xamarin Tips: Check if notification permission got granted for iOS in Xamarin.Forms

We can use DependencyService to check if notifications is enabled for the app.

In iOS:

[assembly: Dependency(typeof(DeviceService))]
  class DeviceService : IDeviceService
  {
    public bool GetApplicationNotificationSettings()
     {
     var settings = UIApplication.SharedApplication.CurrentUserNotificationSettings.Types;
            return settings != UIUserNotificationType.None;
     }
   }

In Forms:

public interface IDeviceService
{
   bool GetApplicationNotificationSettings();
}

And after these, you can call your DependencyService from your page or view model like this:

bool isNotificationEnabled = DependencyService.Get<IDeviceService>().GetApplicationNotificationSettings();
