Question

我想使用MPMoviePlayerController在我的iPad应用中播放视频。我的问题是，该播放器只显示“正在加载”而不播放视频。这是我使用的代码：

- (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，但是成功了。还有，MPMoviePlayerController会播放哪些电影类型？可以因为电影的大小吗？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:

如果您使用上述扩展名播放电影，那么。在您的.h类

中将MPMoivePlayer声明为类类型属性

@property(strong,nonatomic)MPMoviePlayerController *moviePlayer;

在.m

中

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];

MPMoviePlayerController不加载电影
