Question

我有同样的问题： MPMoviewPlayerController fullscreen playback rotation with underlying UIViewController with portrait mode only (rotation disallowed)

我认为这个问题的答案非常有用。然后我为此添加了一个UIViewController。首先：youtubePlayer是一个MPMoviePlayerController，底层代码将youTubeView的框架发送到youtubePlayer并在youTubeView上显示youtubePlayer：

[youtubePlayer.view setFrame:youTubeView.bounds];
[youTubeView addSubview:youtubePlayer.view];

切换到FullScreen后，我想将youtubePlayer.view添加到新的UIViewController，然后它可以自动旋转： playerFullScreen = [[UIViewController alloc] init];

[playerFullScreen.view addSubview:youtubePlayer.view];
[nav pushViewController:playerFullScreen animated:NO];

但是屏幕变白，视频没有显示，我该怎么办？

您不需要使用UIViewController; MPMoviePlayerViewController效果很好，它有自己的功能，可以像YouTube一样以模态方式呈现视频（我认为）。而不是addSubview，请尝试使用setView：

我花了很长时间研究这个，以下工作完美。

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];

//Calls for movie playback once video is finished
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];
playerView = [[MPMoviePlayerViewController alloc]init];
[moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
[playerView setView:moviePlayer.view];

[moviePlayer.view setFrame: self.view.bounds];  // player's frame must match parent's

[self presentMoviePlayerViewControllerAnimated:playerView];

[moviePlayer play];
NSLog(@"playing video view");

并且在解雇其电话时

- (void) moviePlayBackDidFinish:(NSNotification*)notification {
    MPMoviePlayerController *player = [notification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self      
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:player];

    [self dismissMoviePlayerViewControllerAnimated];

    NSLog(@"removed video view");
}

将MPMoviewPlayerController添加到UIViewController以进行全屏播放旋转
