Iphone 在ios6中播放视频

应用程序启动时，视频将自动运行

但按下home（主页）按钮并再次打开，应用程序冻结，不知道原因

我能做什么

- (void)viewDidLoad{

    m_player = [[MPMoviePlayerController alloc] initWithContentURL:url];
            [m_player.backgroundView setBackgroundColor:[UIColor blackColor]];
            [m_player.view setBackgroundColor:[UIColor blackColor]];
            [m_player setControlStyle:MPMovieControlStyleNone];
            [[m_player view] setFrame:[self.view bounds]];

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

            [m_player play];
            [self.view addSubview:[m_player view]];
    }


- (void) moviePlayBackDidFinish:(NSNotification*)_notification
{

        [[NSNotificationCenter defaultCenter] removeObserver:self
                                              name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:nil];

        [m_player.view removeFromSuperview];
        [m_player stop];
        m_player = nil;

    }

}

这段代码帮助我避免在按下home（主页）按钮时冻结应用程序，视频正在播放并正常工作

[[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(handleEnteredBackground:)
                                             name: UIApplicationDidEnterBackgroundNotification
                                           object: nil];




-(void)handleEnteredBackground:(NSNotification*)_notification{

   [m_player play];

}

那么，应用程序完全冻结了，还是只是视频冻结了？请检查crashlog，或者您是否连接到xcode、控制台和共享。可能这就说明了原因。应用程序和视频冻结并显示[MPAVController]自动播放：跳过自动播放，没有足够的缓冲来跟上。
