ios - MPMoviePlayerController 的警告

Question

我正在实现MPMoviePlayerController，我正在使用此方法(presentMoviePlayerViewControllerAnimated)来呈现我的时间

moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlaybackComplete:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayerController];

[moviePlayerController.view setFrame:CGRectMake(0, 0, 320, 480)];

moviePlayerController.controlStyle = MPMovieControlStyleFullscreen;
moviePlayerController.view.userInteractionEnabled =YES;


[self presentMoviePlayerViewControllerAnimated:moviePlayerController];

但是当我演示我正在传递所需的参数时，我收到了不兼容类型的警告。

您正在尝试呈现MPMoviePlayerController而不是MPMoviePlayerViewController这就是警告的原因。

另请记住，MPMoviePlayerViewController 没有 controlStyle 属性

所以使用像:

- (void)showMedia
{
   MPMoviePlayerViewController *moviePlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
   [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlaybackComplete:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayerView.moviePlayer];

   [moviePlayerView.view setFrame:CGRectMake(0, 0, 320, 480)];
   moviePlayerView.view.userInteractionEnabled =YES;
   [self presentMoviePlayerViewControllerAnimated:moviePlayerView];
}
