在 iOS 4 中，这段代码可以播放电影：

-(IBAction)playMovie:(id)sender
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"testbild1" ofType:@"m4v"]];
    MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    UIView *testview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];

    [testview addSubview:moviePlayer.view];
    [self.view addSubview:testview];
    //[self.view addSubview:moviePlayer.view];
    //[moviePlayer setFullscreen:YES animated:YES];
}  

- (void)moviePlaybackComplete:(NSNotification *)notification  
{  
    MPMoviePlayerController *moviePlayerController = [notification object];  
    [[NSNotificationCenter defaultCenter] removeObserver:self  
                                                    name:MPMoviePlayerPlaybackDidFinishNotification  
                                                  object:moviePlayerController];  

    [moviePlayerController.view removeFromSuperview];  
    //[moviePlayerController release];  
}

现在，我只看到黑屏。没有控制，什么都没有。视频路径正确，我测试过。如果我通过单击按钮添加一个白色的子视图，它就可以工作。所以调用该方法。

提前致谢！

In iOS 4 this Code worked to play a movie:

-(IBAction)playMovie:(id)sender
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"testbild1" ofType:@"m4v"]];
    MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    UIView *testview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];

    [testview addSubview:moviePlayer.view];
    [self.view addSubview:testview];
    //[self.view addSubview:moviePlayer.view];
    //[moviePlayer setFullscreen:YES animated:YES];
}  

- (void)moviePlaybackComplete:(NSNotification *)notification  
{  
    MPMoviePlayerController *moviePlayerController = [notification object];  
    [[NSNotificationCenter defaultCenter] removeObserver:self  
                                                    name:MPMoviePlayerPlaybackDidFinishNotification  
                                                  object:moviePlayerController];  

    [moviePlayerController.view removeFromSuperview];  
    //[moviePlayerController release];  
}

Now, I only get a blackscreen. No controls, nothing. Video path is correct, I tested that. If I add just a white Subview by button click, it works. So the method is called.

Thanks in advance!

我通过放入 .h 文件解决了这个问题。

MPMoviePlayerController *moviePlayer;

带有 ARC 的 iOS 5 的工作方式与 iOS 4 不同。.m

文件必须是：

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

I have solved the issue by putting in the .h file

MPMoviePlayerController *moviePlayer;

iOS 5 with ARC works differently than iOS 4.

The .m file must be:

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

如果您使用的是 iOS 5.0 或 5.1，请检查您的 moviePlyer 是否有如下设置。

[moviePlayer setControlStyle:MPMovieControlStyleFullscreen];

如果是这样，当您设置 [moviePlayer setFullScreen:YESanimated:YES];
然后将调用 MPMoviePlayerPlaybackDidFinishNotification 通知，而不是调用 MPMoviePlayerWillExitFullscreenNotification 或 MPMoviePlayerDidExitFullscreenNotification
