MPMoviePlayerController只在通用应用程序中抛出错误

我的应用程序在启动时以全屏模式播放视频。从3.0到4.1,一切都完美无瑕。

然而,如果我为一个通用应用程序编译相同的代码,它将在iPad上工作,但在iPhone(模拟器)上不再工作。

有人解决了这个问题吗?

if ([self respondsToSelector:@selector(presentMoviePlayerViewControllerAnimated:)]) {
  videoPath = [[NSBundle mainBundle] pathForResource:@"portrait" ofType:@"mov"];
  videoURL = [NSURL fileURLWithPath:videoPath];

  MPMoviePlayerController *aMoviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
  self.moviePlayerController = aMoviePlayerController;
  [aMoviePlayerController release];  

  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(startVideo:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
  [moviePlayerController.view setFrame:self.view.bounds];
  [self.view addSubview:moviePlayerController.view];

  moviePlayerController.controlStyle = MPMovieControlStyleNone;
 } else {
  //OS < 3.2
  videoPath = [[NSBundle mainBundle] pathForResource:@"landscape" ofType:@"mov"];
  videoURL = [NSURL fileURLWithPath:videoPath];

  MPMoviePlayerController *aMoviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
  self.moviePlayerController = aMoviePlayerController;
  [aMoviePlayerController release];

  moviePlayerController.movieControlMode = MPMovieControlModeHidden;
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(startVideo:) name:MPMoviePlayerContentPreloadDidFinishNotification object:nil];
 }

这里有个错误:

-[MPMoviePlayerControllerOld view]:发送到实例的无法识别的选择器

0x7924470

if ([moviePlayerController respondsToSelector:@selector(view)]) {
   [moviePlayerController.view setFrame:self.view.bounds];
  }

…错误仍然被抛出。

几天前我也犯了同样的错误。只需将基本sdk从3.2更改为4.1 希望有帮助
