在启动屏幕上全屏播放视频，无需控制

Question

我正在创建一个iPad应用程序，我想在应用程序加载数据时在启动屏幕上全屏播放视频而无需控制，我搜索并找到了一些关于MPPlayerViewController的文章，我使用了它，但我有一些问题如下：

• 我使用以下代码播放视频：

NSString *moviePath = [ [[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"StartupVideo.mp4"];
    moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:moviePath]];
    moviePlayerViewController.view.frame = self.view.bounds;
    [self.view addSubview:moviePlayerViewController.view];
    [self.view sendSubviewToBack:moviePlayerViewController.view];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:[moviePlayerViewController moviePlayer]];
    MPMoviePlayerController *player = [moviePlayerViewController moviePlayer];
    player.fullscreen = YES;
    player.movieSourceType = MPMovieSourceTypeFile;
    player.initialPlaybackTime = -1.0;
    [player play];

一切似乎都正确，但视频未加载，我只看到黑屏。

• 如何在MPVideoPlayerView中隐藏控件？

Answer 1

而不是 [NSURL URLWithString:moviePath]

用

[NSURL fileURLWithString:moviePath]

让我很多次.. :)
