未播放ios应用程序的视频

我试图在点击UITabBar项目时播放视频。我遵循了本教程：

每当我单击UITabBar项时，它只显示普通视图，而不添加电影视图。这是我的密码：

- (void)viewDidLoad {
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                     pathForResource:@"video" ofType:@"m4v"]];
MPMoviePlayerController *moviePlayer =  [[MPMoviePlayerController alloc]
                initWithContentURL:url];

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

moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
}

我还发现以下错误：

2013-01-26 15:21:08.243 Smart Mower[61339:c07] [MPAVController] Autoplay: Disabling        autoplay for pause
2013-01-26 15:21:08.244 Smart Mower[61339:c07] [MPAVController] Autoplay: Disabling autoplay
2013-01-26 15:21:08.260 Smart Mower[61339:c07] [MPAVController] Autoplay: Skipping   autoplay, disabled (for current item: 1, on player: 0)

有人能帮我吗？

谢谢

您好，请尝试添加以下内容

1） 确保在运行时将电影添加到“生成阶段”下的复制包资源中

2） 尝试将代码添加到声明中，如下所示：

            NSString *path = [[NSBundle mainBundle] pathForResource:@"movie" ofType:@"mp4"];
            NSURL *url = [NSURL fileURLWithPath:path];
            moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
            moviePlayer.view.frame = self.view.frame;
            moviePlayer.moviePlayer.shouldAutoplay=YES;
            moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleNone;
           [moviePlayer.moviePlayer setFullscreen:YES animated:YES];
           [self.view addSubview:moviePlayer.view];
           [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(movieFinishedCallback:)
                                           name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer.moviePlayer];

            [moviePlayer.moviePlayer play];

让我知道你是如何表现出来的。

你是如何表现出来的？我确保视频正在添加。用上面的代码替换了我的代码，这些是我单击UITabBar时遇到的错误。我得到了与原始帖子相同的错误，然后我得到了关于CGContext的错误<代码>无效的上下文0x0是，我做了。不过，我用另一种方法解决了这个问题。谢谢你的帮助！
