MPMoviePlayerController堆棧溢出

Question

我想在相當簡單的iPhone應用程序中使用MPMoviePlayerController。基本佈局是與UIWindow xib文件關聯的UIApplicationDelegate。內applicationDidFinishLaunching方法，我試圖播放電影用下面的代碼：

// 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]; 

當此執行，我得到一個「EXC_BAD_ACCESS」錯誤，並且GDB加載一個巨大的堆棧（用「_makeSubtreePerformSelector」方法重複幾千次。

值得一提的是，如果我嘗試播放基於點擊事件電影的代碼，它工作得很好這幾乎就像應用程序沒有完成的「佈線」的東西但關於窗口層次？有沒有人遇到過這樣的事情？

也許你應該嘗試設置animated來編號
