ℹ️ Note: In iOS 8 and above, the airplay button will no longer appear in playback controls. Airplay can be enabled or disabled in the control center.

• Add the following class variable in a UIViewController subclass:

MPMoviePlayerController moviePlayer;

• Add a movie file named sample.m4v to the project in Xamarin or Visual Studio. There is a sample file included in the example project.
• Ensure that the Build Action property of the file is set to Content.
• In the ViewDidLoad method, create the MPMoviePlayer:

moviePlayer = new MPMoviePlayerController (NSUrl.FromFilename("sample.m4v");
moviePlayer.View.Frame = View.Bounds;
moviePlayer.ShouldAutoplay = true; // starts automatically
moviePlayer.PrepareToPlay (); //required to enable the control to start playing

• To enable AirPlay for this movie, set AllowsAirPlay to true:

moviePlayer.AllowsAirPlay = true;

• To disable AirPlay, set AllowsAirPlay to false:

moviePlayer.AllowsAirPlay = false;
