我的MPMediaPlayerController怎么了？

Question

大家好，我在iPhone开发中创建了一个简单的电影播放器。但我只能听到维迪奥的声音。这是我的代码(单击按钮时)，

-(IBAction)playMe{
    NSBundle *bundle=[NSBundle mainBundle];
    NSString *moviePath=[bundle pathForResource:@"iiii" ofType:@"mp4"];
    NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
    MPMoviePlayerController *theMovie=[[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    theMovie.scalingMode = MPMovieScalingModeAspectFill;

    [theMovie play];
    [self.view addSubview:theMovie.view];
}

当我点击的时候，我得到的只是声音而不是电影。我还使用了iOS 4.1模拟器。

Answer 1

这可能是因为您没有设置帧显示电影播放器尝试此。

theMovie.view.frame=CGRectMake(0,0,300.400);

如果这不起作用，您可以查看以下教程
