在热点时全屏调整窗口大小时AVPlayer崩溃

Question

我在一个应用程序上编码,用户可以观看各种各样的视频.我在按钮点击时全屏打开视频,用户可以使用播放控件来调整窗口大小.我遇到的问题是当用户通过热点共享他的互联网时,应用程序顶部有一个蓝色条.此时调整窗口大小会导致AVKit框架崩溃(我相信).使用Swift 2.3,Xcode 7.3.1.我的手机,iPhone 6s,使用iOS 10,我也尝试过iOS 9 iPhone 6 Plus,同样的问题.

碰撞:

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<AVFullScreenPlaybackControlsViewController: 0x102933000> should have parent view controller:<AVPlayerViewController: 0x10212d800> but actual parent is:<AVFullScreenViewController: 0x10884d900>'

我的代码:

private let playerController = AVPlayerViewController()
private var player: AVPlayer!

private func playVideo(media: Media) {

        player = AVPlayer(URL: NSURL(string: media.url)!)
        playerController.player = player

        presentViewController(playerController, animated: true, completion: {
            self.playerController.player?.play()
            self.playerController.delegate = self
        })

    }

如果我不在我的手机上共享我的互联网(因此没有蓝色条),那么它工作正常,没有任何问题.有人设法隐藏这个蓝色条,或遇到类似的问题？

作为一种解决方法，您可以推送 navigationControlelr 堆栈，或者在以模式方式呈现时使用此：

@interface AVPlayerViewController ()
- (void)fullScreenButtonTapped:(id)arg1;
@end

@interface RCKPlayerViewController ()

@end

@implementation RCKPlayerViewController

- (void)fullScreenButtonTapped:(id)arg1 {
    if ([[UIApplication sharedApplication] statusBarFrame].size.height >= 40) {
        // Show alert that cannot enter full screen when in-call
    } else {
        [super fullScreenButtonTapped:arg1];
    }
}

@end

然后只需使用RCKPlayerViewController

AVPlayerViewController *playerViewController = [[RCKPlayerViewController alloc] init];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:videoStringURL]];
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];
playerViewController.player = player;

[self presentViewController:playerViewController animated:YES completion:^{
    [player play];
}];
