mediaremoted 在 iOS5 中给出属性列表错误

我有一个正在迁移到 iOS5 的应用程序，在模拟器中运行时，我看到大量这样的消息：

10/25/11 10:34:43.002 AM mediaremoted: Property list invalid for format: 200 (property lists cannot contain NULL)
10/25/11 10:34:43.003 AM mediaremoted: Property list invalid for format: 200 (property lists cannot contain NULL)

在我使用以下代码将电影加载到 MPMoviePlayerViewController 后立即发出：

if (moviePath)
{
  movieURL = [NSURL fileURLWithPath:moviePath];

  // this next line will throw these messages
  MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];

  [view presentMoviePlayerViewControllerAnimated:mpvc];
  [(AppDelegate *)[[UIApplication sharedApplication] delegate] setMoviePlayerVC:mpvc];

}

我根本不清楚什么“属性列表”是导致此错误消息的原因，因为此时似乎没有读取任何内容。我倾向于相信这可能是一个转移注意力的事情。任何想法都会有帮助

I have an app I'm migrating to iOS5, when running in the simulator, I see a slew of messages like this:

10/25/11 10:34:43.002 AM mediaremoted: Property list invalid for format: 200 (property lists cannot contain NULL)
10/25/11 10:34:43.003 AM mediaremoted: Property list invalid for format: 200 (property lists cannot contain NULL)

being issued right after I load a movie into a MPMoviePlayerViewController with the following code:

if (moviePath)
{
  movieURL = [NSURL fileURLWithPath:moviePath];

  // this next line will throw these messages
  MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];

  [view presentMoviePlayerViewControllerAnimated:mpvc];
  [(AppDelegate *)[[UIApplication sharedApplication] delegate] setMoviePlayerVC:mpvc];

}

it's not at all clear to me what "property list" is responsible for this error message, as none seems to being read at this point. I'm inclined to believe that this may be a red-herring. Any thoughts would be helpful
