MPMoviePlayerController不加载电影

Question

我想使用MPMoviePlayerController在我的iPad应用程序中播放视频。我的问题是，该播放器只显示“加载”，不播放视频。下面是我的代码使用方法：

- (void)playMovieFile:(NSString *)fileName 
{ 
    NSString *filePath=[[NSBundle mainBundle] pathForResource:fileName ofType:@"mov"]; 
    NSURL *fileUrl=[NSURL fileURLWithPath:filePath]; 

    self.moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:fileUrl]; 
    [self.moviePlayer.view setFrame:self.view.frame]; 

    [self.view addSubview:self.moviePlayer.view]; 
    [self.moviePlayer prepareToPlay]; 
    [self.moviePlayer play]; 
} 

我也尝试使用MPMoviePlayerViewController，但神志清醒success.Also，什么电影类型做的MPMoviePlayerController播放？这是因为电影的大小吗？它是263 MB。

iPhone支持的电影格式为.mov, .m4v, mp4 or 3gp。

The video technologies in iOS support the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

如果您在播放电影与上述的扩展即可。声明你的MPMoivePlayer作为类的类型属性在.h类

@property(strong,nonatomic)MPMoviePlayerController *moviePlayer; 

在.m

NSString *filePath=[[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"mov"]; 

NSURL *fileUrl=[NSURL fileURLWithPath:filePath]; 

self.moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:fileUrl]; 
[self.moviePlayer.view setFrame:CGRectMake(x,y,width,height)]; 

[self.view addSubview:self.moviePlayer.view]; 
[self.moviePlayer prepareToPlay]; 
[self.moviePlayer play];
