MPMoviePlayerViewController setFullScreen：顯示白色屏幕

Question

我想將mp4視頻設置爲全屏，並且它看起來很簡單，但每當我調用setFullscreen方法時，它就會變成白色的空白屏幕。有任何想法嗎？這裏是我的代碼：

- (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]; 
} 

如果我註釋掉最後一行，視頻將發揮，但不知何故整個屏幕變成白色屏幕，而不是僅僅最大化視頻。

謝謝。

我有一個類似的問題，這段代碼爲我工作。

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

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