MPMoviePlayerViewController不顯示音量滑塊？

Question

我玩視頻從URL：

MPMoviePlayerViewController *m = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; 

    if([m.moviePlayer respondsToSelector:@selector(setAllowsAirPlay:)]) 
     m.moviePlayer.allowsAirPlay = YES; 
    [self presentMoviePlayerViewControllerAnimated:m]; 

是玩，但沒有音量控制滑塊。是否可以添加音量控制？

您可以使用MPVolumeView對象。

volume = [[MPVolumeView alloc] initWithFrame: rect]; 
[self addSubview:volume];
