Question

我遇到了问题：我向MPMoviePlayerViewController添加了detailView，但是当我点击按钮打开detailView时，MPMoviePlayerViewController会自动在FUllScreen模式下播放。现在我想要点击按钮打开DetailView，MPMoviePlayerViewController显示播放按钮而不是自动播放。然后用户单击“播放”按钮，MPMoviePlayerViewController必须通过调用[self presentMoviePlayerViewControllerAnimated:moviePlayer];在FULLScreen中运行。我怎样才能做到这一点？提前谢谢。

movieURL = [NSURL URLWithString:previewString];

    moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
    moviePlayer.view.frame = CGRectMake(10,130, 275 , 150);
    [moviePlayer.moviePlayer prepareToPlay] ;
    moviePlayer.moviePlayer.shouldAutoplay = NO;
    moviePlayer.wantsFullScreenLayout = NO;
    moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
    //[detailview addSubview:moviePlayer.view];
    [self presentMoviePlayerViewControllerAnimated:moviePlayer];

如果尝试上面的代码，moviePlayer会自动在FULLSCREEN模式下运行。现在我想在开始时，moviePlayer不会在FULLSCREEN模式下自动运行，当用户点击Play按钮时，它将以FULLSCREEN模式运行。

要求通知播放状态已更改：

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(mpChangedPlaybackState:)
                                             name:MPMoviePlayerPlaybackStateDidChangeNotification
                                           object:nil];

然后检查播放状态以查看它是否正在播放：

- (void)mpChangedPlaybackState:(NSNotification *)notification {

    if (self.moviePlayer.playbackState == MPMoviePlaybackStatePlaying) {
        // the state has changed to 'playing'
    }
}

当你不再需要知道时（最迟在viewWillDisappear:上）

，请记得以观察者身份移除自己
