DidEnterFullscreen 的通知常數
[Foundation.Advice("Use MPMoviePlayerController.Notifications.ObserveDidEnterFullscreen helper method instead.")]
[Foundation.Field("MPMoviePlayerDidEnterFullscreenNotification", "MediaPlayer")]
[ObjCRuntime.Deprecated(ObjCRuntime.PlatformName.iOS, 9, 0, ObjCRuntime.PlatformArchitecture.All, "Use 'AVPlayerViewController' (AVKit) instead.")]
[ObjCRuntime.Unavailable(ObjCRuntime.PlatformName.WatchOS, ObjCRuntime.PlatformArchitecture.All, null)]
public static Foundation.NSString DidEnterFullscreenNotification { [ObjCRuntime.Deprecated(ObjCRuntime.PlatformName.iOS, 9, 0, ObjCRuntime.PlatformArchitecture.All, "Use 'AVPlayerViewController' (AVKit) instead.")] [ObjCRuntime.Unavailable(ObjCRuntime.PlatformName.WatchOS, ObjCRuntime.PlatformArchitecture.All, null)] get; }

屬性值
NSString 常數應該用來做為 NSNotificationCenter 的權杖。

備註
這個常數可以搭配 使用 NSNotificationCenter ,以註冊此通知的接聽程式。 這是 NSString 而非字串,因為這些值可以當做某些原生程式庫中的權杖使用,而不是單純用於其實際字串內容。 回呼的 'notification' 參數包含通知類型特有的額外資訊。
如果您想要訂閱此通知,您可以使用便利性 MPMoviePlayerController.Notifications 。M:MPMoviePlayerController.Notifications.ObserveDidEnterFullscreen* 方法,可提供對通知參數的強型別存取。
下列範例示範如何使用強型別的 Notifications 類別,來排除通知中可用屬性的猜測:
//
// Lambda style
//
// listening
notification = MPMoviePlayerController.Notifications.ObserveDidEnterFullscreen ((sender, args) => {
/* Access strongly typed args */
Console.WriteLine ("Notification: {0}", args.Notification);
});
// To stop listening:
notification.Dispose ();
//
// Method style
//
NSObject notification;
void Callback (object sender, Foundation.NSNotificationEventArgs args)
{
// Access strongly typed args
Console.WriteLine ("Notification: {0}", args.Notification);
}
void Setup ()
{
notification = MPMoviePlayerController.Notifications.ObserveDidEnterFullscreen (Callback);
}
void Teardown ()
{
notification.Dispose ();
}
下列範例示範如何搭配 DefaultCenter API 使用通知:
// Lambda style
NSNotificationCenter.DefaultCenter.AddObserver (
MPMoviePlayerController.DidEnterFullscreenNotification, (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.DidEnterFullscreenNotification, Callback);
}
