MPMoviePlayerViewController setFullScreen：显示白色屏幕

Question

我想将mp4视频设置为全屏，并且它看起来很简单，但每当我调用setFullscreen方法时，它就会变成白色的空白屏幕。有任何想法吗？这里是我的代码：

- (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，视频将发挥，但不知何故整个屏幕变成白色屏幕，而不是仅仅最大化视频。

谢谢。

我有一个类似的问题，这段代码为我工作。

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

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