AVPlayerController - 按钮无法全屏工作

Question

我正在尝试了解 AVPlayer 和 AVPlayerController 的工作原理。我将我的播放器嵌入到一个视图中，所以我的播放器有两种模式：小屏幕和全屏。当它很小时，play/plause 按钮和全屏按钮工作得很好。但是一旦全屏，以下按钮将不起作用：播放、暂停、完成、最小化。

这是我的代码：

    let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
    let avPlayer:AVPLayer = AVPlayer(url: videoURL! as URL)
    let playerController = AVPlayerViewController()
    playerController.player = avPlayer
    playerController.view.backgroundColor = UIColor.racingGreenColor();
    playerController.view.translatesAutoresizingMaskIntoConstraints = false;
    playerController.showsPlaybackControls = true;
    self.middleView.addSubview(playerController.view)
    //avPlayer.play()

    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .width, relatedBy: .equal, toItem: self.middleView, attribute: .width, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .height, relatedBy: .equal, toItem: self.middleView, attribute: .height, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .centerX, relatedBy: .equal, toItem: self.middleView, attribute: .centerX, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .centerY, relatedBy: .equal, toItem: self.middleView, attribute: .centerY, multiplier: 1, constant: 0));

有人可以帮我吗？有我感兴趣的 4 种方法的委托吗？

Answer 1

它对我有用 self.present(playerController, animated: true, completion:nil)

既然是控制器，我们就应该把它当作控制器来使用，而不是作为子视图来使用。

Answer 2

您可以将 AVPlayer 添加为图层，并添加您自己的自定义按钮

播放器 = [[[AVPlayer 分配] 初始化...

playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
CGSize size = self.view.bounds.size;
float x = size.width/2.0-187.0;
float y = size.height/2.0 - 125.0;

playerLayer.frame = CGRectMake(x, y, 474, 320);
[playerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
[self.view.layer addSublayer:playerLayer];
[player play];

Answer 3

self.addChildController(playerController);

我已将它添加到您的主视图控制器上，它可以为 "Done" 和 "Minimise" 提供帮助。
