Question

我知道，有几十个类似的问题。我读完了所有内容，但仍无法找到答案。我通过presentModalViewController方法显示带有视频的视图。当用户进行滑动时，我希望下一个视频可以在同一个播放器中启动。但是当我尝试更改视频播放器的contentURL时，视图会消失 - 就像调用了dismissModalViewControllerAnimated方法一样（但事实并非如此）。

@implementation ViewController

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

    if(!moviePlayerViewController)
    {
        NSURL *url = [NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8"];

        moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];       

        UISwipeGestureRecognizer *leftSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipe:)];
        leftSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
        [moviePlayerViewController.view addGestureRecognizer:leftSwipeRecognizer];

        [self presentModalViewController:moviePlayerViewController animated:YES];
    }
}

-(void)leftSwipe:(id)sender
{
    moviePlayerViewController.moviePlayer.contentURL = 
        moviePlayerViewController.moviePlayer.contentURL; // no matter what exactly URL here.
    [moviePlayerViewController.moviePlayer play]; // view disappears even before this line is reached
}

@end

奇怪的是：我昨天花了整整一天试图找到一个徒劳的答案，我在这里发布问题后一分钟就找到了答案。
