Ios 使用MPMoviePlayerController发出警告

我是MPMoviePlayerController的实现者，我正在使用此方法（PresentMoviePlayerServiceController激活）在我

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，当我演示时，我得到了警告不兼容类型。我正在传递所需的参数。

您演示的不是视图控制器，而是MPMoviePlayerController。那是另一个对象。如果要在视图控制器中显示电影播放器控制器，请尝试使用MPMoviePlayerViewController。

您尝试的是显示而不是显示，这就是警告出现的原因

还要记住，

mpmovieplayervewcontroller

因此，请使用以下命令：

- (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];
}
