MPMoviePlayerViewController setFullScreen：显示白屏

Question

我想将 mp4 视频设置为全屏，这看起来很简单，但是每当我调用 setFullscreen 方法时，它就会变成一个白色的空白屏幕。有任何想法吗？这是我的代码：

- (void)tableView:(UITableView *)aTableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
......
moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:movpath]];
[self presentModalViewController:moviePlayerViewController animated:YES];

moviePlayerController = [moviePlayerViewController moviePlayer];
[moviePlayerController prepareToPlay];

[[moviePlayerViewController moviePlayer] play]; 
[[moviePlayerViewController moviePlayer] setFullscreen:YES animated:YES];
}

如果我注释掉最后一行，视频会播放，但不知何故，全屏变成了白屏，而不仅仅是最大化视频。

谢谢。

我遇到了类似的问题，这段代码对我有用。

MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:URL]];

            [moviePlayer.view setBackgroundColor:[UIColor blackColor]];
            [moviePlayer.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
            [self presentMoviePlayerViewControllerAnimated:moviePlayer];
            [moviePlayer.moviePlayer play];
