Question

我有一个导航控制器，可以推送播放视频文件的另一个视图。一切都很好，在模拟器上没有任何问题。问题是当我在iPhone上测试应用程序时，电影播放效果不错但是如果我按下iPhone上的主页按钮然后再次启动应用程序我在Xcode调试区域收到以下警告：

2011-11-21 20：23：05.216 KMW [324：707] MP _playbackInterruptionDidEndNotification :: NSConcreteNotification 0x164e90 {name = AVController_PlaybackInterruptionDidEndNotification; object =; userInfo = { “AVController_InterruptionStatusNotificationParameter”=“non-resumable.SoloAmbientSound”; “AVController_InterruptorNameNotificationParameter”=“AudioSession-324”; }，_state = 0

虽然出现了此警告，但我可以继续使用该应用程序并观看电影而不会出现任何问题，但我担心在某种情况下此警告会导致问题。以下是我如何设置播放电影的视图：

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"movieFileName" ofType:@"m4v"];
    movieURL = [NSURL fileURLWithPath:path];
    self.moviePlayer = [[[MPMoviePlayerController alloc] initWithContentURL:movieURL] autorelease];

    [self.view addSubview:moviePlayer.view];
    moviePlayer.view.frame = CGRectMake(0, 10, 320, 181);
    [moviePlayer setControlStyle:MPMovieControlStyleNone];
    [moviePlayer play];
}

- (void) viewWillDisappear:(BOOL)animated
{
    [moviePlayer stop];
    [moviePlayer.view removeFromSuperview];
}

- (void)dealloc
{
    [movieURL release];
    [moviePlayer release];
    [super dealloc];
}

关于这个奇怪警告的任何想法？

MPMoviePlayerController在appDidBecomeActive上导致MP _playbackInterruptionDidEndNotification
