MPMoviePlayerViewController setFullScreen：显示白色屏幕

Question

我想将mp4视频设置为全屏，看起来很简单，但每当我调用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，视频将播放，但不知何故全屏变为白色屏幕，而不是仅仅最大化视频。

感谢。

我有类似的问题，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];
