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？

Answer 1

我通过这段代码修复了它：

@interface YourAVPlayerViewController : AVPlayerViewController
@end

@implementation YourAVPlayerViewController

 - (BOOL)prefersStatusBarHidden {
        return YES;
 }

@end

Answer 2

作为一种解决方法，您可以推送navigationControlelr堆栈或在呈现模态时使用以下内容：

@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];
}];

Answer 3

我为AVPlayerViewController编写了一个小扩展，修复了应用程序范围内的问题：

// AVPlayerViewController.swift

import AVKit

extension AVPlayerViewController {

  // fixes app crash while using personal hotspot + watching a full screen video
  override open var prefersStatusBarHidden: Bool {
    return true
  }

}
