带有UIModalPresentationPageSheet的MPMoviePlayerController

Question

我在我的iPad应用程序上将一个电影播放器​​绘制到我的视图控制器上。视图使用UIModalPresentationPageSheet以模态方式显示。

视频显示正确，但全屏时，“完成”和“比率”按钮似乎无效。如何启用这些按钮，以便在更改比率时退出全屏。

以下是我用于创建电影播放器​​的代码

NSString *url = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"m4v"];
NSURL *strURL =[NSURL URLWithString:url];

player = [[MPMoviePlayerController alloc] initWithContentURL:strURL];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enteredFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[player setMovieSourceType:MPMovieSourceTypeFile];


//---play partial screen---
player.view.frame = CGRectMake(0, 42 , 780, 300);
[player prepareToPlay]; // this had to be in for it to work

[self.view addSubview:player.view];
player.shouldAutoplay = NO;

由于
