ios - 视频不播放 ios 应用

Question

单击 UITabBar 项目时，我正在尝试播放视频。我遵循了本教程：http ://www.techotopia.com/index.php/Video_Playback_from_within_an_iOS_5_iPhone_Application

每当我单击 UITabBar 项目时，它只会显示普通视图，不会添加电影视图。这是我的代码：

- (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];
}

我也收到以下错误：

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)

有人可以帮我吗？谢谢！

你好尝试添加一些这些东西。

1) 确保在运行时将您的电影添加到构建阶段下的复制包资源中。

2）尝试为您的声明添加代码，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];

让我知道你是怎么出来的。
