MPMoviePlayerController堆栈溢出

Question

我想在相当简单的iPhone应用程序中使用MPMoviePlayerController。基本布局是与UIWindow xib文件关联的UIApplicationDelegate。内applicationDidFinishLaunching方法，我试图播放电影用下面的代码：

// Path to the movie 
NSString *path = [[NSBundle mainBundle] pathForResource:@"logoscreen" ofType:@"m4v"];  
movieURL = [NSURL fileURLWithPath:path]; 

// Setup the player 
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; 

// Use the new 3.2 style API 
moviePlayer.controlStyle = MPMovieControlStyleNone; 
moviePlayer.shouldAutoplay = YES; 
[window addSubview:moviePlayer.view]; 

[moviePlayer setFullscreen:YES animated:YES]; 

当此执行，我得到一个“EXC_BAD_ACCESS”错误，并且GDB加载一个巨大的堆栈（用“_makeSubtreePerformSelector”方法重复几千次。

值得一提的是，如果我尝试播放基于点击事件电影的代码，它工作得很好这几乎就像应用程序没有完成的“布线”的东西但关于窗口层次？有没有人遇到过这样的事情？

也许你应该尝试设置animated来编号
