iphone - MPMoviePlayerViewController - 更改全屏时如何在 MPMoviePlayerViewController 上保留图像？

Question

NSURL *url = [self localMovieURL];
MPMoviePlayerViewController *playerView = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
MPMoviePlayerController *moviePlayer = [playerView moviePlayer];

moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.scalingMode = MPMovieControlStyleFullscreen;

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];

[self setMessageLabel];
[playerView.view addSubview:message];

[self.navigationController presentMoviePlayerViewControllerAnimated:playerView];

你好，

出了点问题.. mpMoviePlayerViewController。

source > 'message (UILabel)' 是全局变量。

视频播放>全屏按钮单击>消失标签...

我不知道为什么没有标签。

请任何人帮助我。

只是预感，但您应该尝试遵循MPMoviePlayerDidEnterFullscreenNotification通知，然后在通知处理程序中执行以下操作，

[message.superview bringSubviewToFront:message];
