ios - 如何在 iOS 中运行 MPMoviePlayerViewController 时禁用 FULLScreen 模式

Question

我有一个问题:我将 MPMoviePlayerViewController 添加到 detailView，但是当我单击按钮打开 detailView 时，MPMoviePlayerViewController 在全屏模式下自动播放。现在我希望当单击按钮打开 DetailView 时，MPMoviePlayerViewController 显示播放按钮而不是自动播放。然后用户点击播放按钮，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？提前致谢。

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 会自动以全屏模式运行。现在我希望当开始时，moviePlayer 不会在全屏模式下自动运行，当用户点击播放按钮时，它会在全屏模式下运行。

请求通知播放状态已更改:

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

然后查看播放状态，看是否正在播放:

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

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

当您不再需要知道时(最晚在 viewWillDisappear: 上)记得移除自己作为观察者
