MPMoviePlayerController不加載電影

Question

我想使用MPMoviePlayerController在我的iPad應用程序中播放視頻。我的問題是，該播放器只顯示「加載」，不播放視頻。下面是我的代碼使用方法：

- (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]; 
} 

我也嘗試使用MPMoviePlayerViewController，但神志清醒success.Also，什麼電影類型做的MPMoviePlayerController播放？這是因爲電影的大小嗎？它是263 MB。

iPhone支持的電影格式爲.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:

如果您在播放電影與上述的擴展即可。聲明你的MPMoivePlayer作爲類的類型屬性在.h類

@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];
