Property Value

NSString constant, should be used as a token to NSNotificationCenter.

Attributes

Remarks

This constant can be used with the NSNotificationCenter to register a listener for this notification. This is an NSString instead of a string, because these values can be used as tokens in some native libraries instead of being used purely for their actual string content. The 'notification' parameter to the callback contains extra information that is specific to the notification type.

To subscribe to this notification, developers can use the convenience MPMoviePlayerController.Notifications.ObserveThumbnailImageRequestDidFinish method which offers strongly typed access to the parameters of the notification.

The following example shows how to use the strongly typed Notifications class, to take the guesswork out of the available properties in the notification:


//
// Lambda style
//

// listening notification = MPMoviePlayerController.Notifications.ObserveThumbnailImageRequestDidFinish ((sender, args) => { /* Access strongly typed args */ Console.WriteLine ("Notification: {0}", args.Notification);

Console.WriteLine ("Image", args.Image);
Console.WriteLine ("Time", args.Time);
Console.WriteLine ("Error", args.Error);

});

// To stop listening: notification.Dispose ();

// // Method style // NSObject notification; void Callback (object sender, MediaPlayer.MPMoviePlayerThumbnailEventArgs args) { // Access strongly typed args Console.WriteLine ("Notification: {0}", args.Notification);

Console.WriteLine ("Image", args.Image);
Console.WriteLine ("Time", args.Time);
Console.WriteLine ("Error", args.Error);

}

void Setup () { notification = MPMoviePlayerController.Notifications.ObserveThumbnailImageRequestDidFinish (Callback); }

void Teardown () { notification.Dispose (); }

The following example shows how to use the notification with the DefaultCenter API:


// Lambda style
NSNotificationCenter.DefaultCenter.AddObserver (
        MPMoviePlayerController.ThumbnailImageRequestDidFinishNotification, (notification) => {Console.WriteLine ("Received the notification MPMoviePlayerController", notification); }

// Method style void Callback (NSNotification notification) { Console.WriteLine ("Received a notification MPMoviePlayerController", notification); }

void Setup () { NSNotificationCenter.DefaultCenter.AddObserver (MPMoviePlayerController.ThumbnailImageRequestDidFinishNotification, Callback); }
