Iphone MPMoviePlayerController仅在通用应用程序中抛出错误

当应用程序启动时，我的应用程序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

代码如下：

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];
 }

…错误仍然被抛出。

我还没有解释错误的原因。但这似乎可行（需要在旧设备上测试）：

if（[self respondsToSelector:@selector（presentmovieplayervicewcontrolleranimated:））{
videoPath=[[NSBundle mainBundle]pathForResource:@“肖像”类型：@“mov”]；
videoURL=[NSURL fileURLWithPath:videoPath]；
/*新的*/
MPMoviePlayerViewController*aMoviePlayerViewController=[[MPMoviePlayerViewController alloc]initWithContentURL:videoURL]；
amovieplayervewcontroller.moviePlayer.view.frame=self.view.bounds；
amovieplayervewcontroller.moviePlayer.controlStyle=MPMovieControlStyleNone；
[[NSNotificationCenter defaultCenter]添加观察者：自选择器：@selector（startVideo:）名称：MPMoviePlayerLoadStateDidChangeNotification对象：nil]；
[amovieplayervewcontroller.moviePlayer play]；
[self.view addSubview:amovieplayervewcontroller.view]；
self.moviePlayerController=amovieplayervewcontroller；
}否则{
//OS<3.2
videoPath=[[NSBundle mainBundle]pathForResource:@“横向”类型：@“mov”]；
videoURL=[NSURL fileURLWithPath:videoPath]；
MPMoviePlayerController*aMoviePlayerController=[[MPMoviePlayerController alloc]initWithContentURL:videoURL]；
self.moviePlayerController=aMoviePlayerController；
aMoviePlayerController.movieControlMode=MPMovieControlModeHidden；
[[NSNotificationCenter defaultCenter]添加观察者：自选择器：@selector（startVideo:）名称：MPMoviePlayerContentPrelodFinishNotification对象：nil]；
[aMoviePlayerController释放]；
}

要是我能记得当初为什么用另一种方式做那件事就好了；）

我几天前也犯了同样的错误。它只需要将基本sdk从3.2更改为4.1

希望有帮助

是的，这就解决了问题。谢谢你，马西奥！

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

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

        /* NEW */
        MPMoviePlayerViewController *aMoviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];
        aMoviePlayerViewController.moviePlayer.view.frame = self.view.bounds;
        aMoviePlayerViewController.moviePlayer.controlStyle = MPMovieControlStyleNone;
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(startVideo:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
        [aMoviePlayerViewController.moviePlayer play];
        [self.view addSubview:aMoviePlayerViewController.view];
        self.moviePlayerController = aMoviePlayerViewController;


    } else {
