iphone - 如何在 iPhone 上捕获 MPMoviePlayer 进度条轨道事件

Question

在我的应用程序中，我使用 MPMoviePlayerController 来播放视频。我想在用户尝试跳过电影时捕获该事件(跟踪进度条)。

在此之前澄清我的疑问，当用户尝试跳过视频(跟踪进度条)时是否有可能获取该事件。

谢谢:)

为 MPMoviePlayerController 定义了许多通知

//当缩放模式改变时发布。

MP_EXTERN NSString *const MPMoviePlayerScalingModeDidChangeNotification;

// Posted when movie playback ends or a user exits playback.
MP_EXTERN NSString *const MPMoviePlayerPlaybackDidFinishNotification;

MP_EXTERN NSString *const MPMoviePlayerPlaybackDidFinishReasonUserInfoKey NS_AVAILABLE_IPHONE(3_2); // NSNumber (MPMovieFinishReason)

// Posted when the playback state changes, either programatically or by the user.
MP_EXTERN NSString *const MPMoviePlayerPlaybackStateDidChangeNotification NS_AVAILABLE_IPHONE(3_2);

// Posted when the network load state changes.
MP_EXTERN NSString *const MPMoviePlayerLoadStateDidChangeNotification NS_AVAILABLE_IPHONE(3_2);

// Posted when the currently playing movie changes.
MP_EXTERN NSString *const MPMoviePlayerNowPlayingMovieDidChangeNotification NS_AVAILABLE_IPHONE(3_2);

// Posted when the movie player enters or exits fullscreen mode.
MP_EXTERN NSString *const MPMoviePlayerWillEnterFullscreenNotification NS_AVAILABLE_IPHONE(3_2);
MP_EXTERN NSString *const MPMoviePlayerDidEnterFullscreenNotification NS_AVAILABLE_IPHONE(3_2);
MP_EXTERN NSString *const MPMoviePlayerWillExitFullscreenNotification NS_AVAILABLE_IPHONE(3_2);
MP_EXTERN NSString *const MPMoviePlayerDidExitFullscreenNotification NS_AVAILABLE_IPHONE(3_2);
MP_EXTERN NSString *const MPMoviePlayerFullscreenAnimationDurationUserInfoKey NS_AVAILABLE_IPHONE(3_2); // NSNumber of double (NSTimeInterval)
MP_EXTERN NSString *const MPMoviePlayerFullscreenAnimationCurveUserInfoKey NS_AVAILABLE_IPHONE(3_2);     // NSNumber of NSUInteger (UIViewAnimationCurve)
