Question

现在我想我知道3.X和4之间在MPMoviePlaybackController方面的差异以及需要设置视图并让它在子视图控制器中完全工作。但是，尽管以下代码看起来是正确的（对我而言），我仍然只是在电影的持续时间内得到一个空白屏幕。我知道它会成功播放，因为moviePlayBackDidFinish会触发。

此时我是否需要将其添加到模态或类似物中？

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

    MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:filePath]];

     player.fullscreen = YES;
     player.controlStyle = MPMovieControlStyleNone;
     [[player view] setFrame:window.bounds];
     [window addSubview: [player view]];

     [[NSNotificationCenter defaultCenter] addObserver:self 
                selector:@selector(moviePlayBackDidFinish:) 
                 name:MPMoviePlayerPlaybackDidFinishNotification 
                  object:player]; 
}

Answer 1

~~MPMoviePlayerController没有view属性。您应该/必须使用MPMoviePlayerViewController。~~

这就是我的所作所为：

        moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:currentChannel.StreamURI]];

    [moviePlayerViewController.moviePlayer setControlStyle:MPMovieControlStyleNone];
    moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    moviePlayerViewController.moviePlayer.shouldAutoplay = YES;
    [moviePlayerViewController.moviePlayer setScalingMode: MPMovieScalingModeAspectFit];
    moviePlayerViewController.view.frame = CGRectMake(0, 0, 480, 320); 


    [self.view addSubview:moviePlayerViewController.view];

请注意，您可能希望将movieSourceType更改为MPMovieSourceTypeFile或MPMovieSourceTypeUnknown。上面的代码是我播放电影所需的100％（在我的情况下是一个流媒体频道）

Answer 2

在我的情况下，我移动了

[window makeKeyAndVisible];

从

出来

didFinishLaunchingWithOptions

进入我的

movieDidFinish

通过把它放回去工作
