Iphone mpmovieplayervewcontroller的子类不'；t-目标C

我已经对MPMoviePlayServiceWController子类化了

MPMoviePlayServiceWController

，方法

[parentViewController DismissMoviePlayServiceControllerAnimated]

不会将其动画化。玩家消失了。即使没有手动关闭它，只需按“完成”按钮，播放器也会在没有动画的情况下消失。在子类播放器中，我将按钮添加到我的播放器视图中，就是这样。问题出在哪里？下面是一些初始化我的播放器的代码

MyMovieViewController *playerView = [[[MyMovieViewController alloc] initWithContentURL:url] autorelease];
[playerView setSelectedVideo:video];
[playerView.moviePlayer setAllowsAirPlay:YES];
[playerView.moviePlayer setShouldAutoplay:YES];
[[MenuController sharedInstance].menuView setHidden:YES];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playBackChanged:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:playerView.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadStateChanged:) name:MPMoviePlayerLoadStateDidChangeNotification object:playerView.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playBackChanged:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerView.moviePlayer];
[self presentMoviePlayerViewControllerAnimated:playerView];

[自我解除ModalViewController激活：是]
当使用MPMoviePlayerServiceWController时，您应该改为使用。没有帮助：（我将MyMovieViewController更改为MPMoviePlayServiceWController，它没有任何关闭方法。我只需点击“完成”按钮，播放器就会关闭动画。您是在
MPMoviePlayServiceController
子类的实例上还是在其父viewController上调用该方法？后者是正确的。@直到我从m父视图控制器
