嗨，我已经在 MPMoviePlayerController 上工作，但现在我面临着这个问题，我可能是 xcode 或 ios 的版本问题
NSString*theMoviePath=[NSString stringWithFormat:@"%@/9441426768774.mp4", [[AppDelegate appdelegate] getDocumentDirectoryPath]];
AnandLog(@"theMovieURL :--->%@", theMoviePath);
NSURL*theMovieURL=[NSURL fileURLWithPath:theMoviePath];
self.moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:theMovieURL];
[self.moviePlayer.view setFrame:CGRectMake(40, 197, 240, 160)];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setShouldAutoplay:NO];
// And other options you can look through the documentation.
[self.view addSubview:self.moviePlayer.view];
错误

我的想法是问题问题可能出在xcode6.2 和 ios8.2 中，以前有人处理过这种情况吗？
指导我解决这个问题。
