ios - 如何在 AVPlayerViewController 中播放视频时快速检测触摸

Question

我以编程方式将 AVPlayerViewController 添加到 UIViewController。当玩家完成播放 (playerDidFinishPlaying) 时，我能够收到通知。我还想知道是否有用户在播放视频时触摸了屏幕，我没有发现任何相关通知。

Answer 1

解决方案是创建一个 AVPlayerViewController 的 Base 类并覆盖 touches​Began(_:​with:​)方法:

swift 2:

自定义基类:

class CustomAVPlayerViewController: AVPlayerViewController {
    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        print("touchesBegan")
    }
}

View Controller :

let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(URL: videoURL!)
let playerViewController = CustomAVPlayerViewController()
playerViewController.player = player
self.presentViewController(playerViewController, animated: true) {
    playerViewController.player!.play()
}

swift 3:

自定义基类:

class CustomAVPlayerViewController: AVPlayerViewController {
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        print("touchesBegan")
    }
}

View Controller :

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerViewController = CustomAVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
    playerViewController.player!.play()
}

不要忘记import AVKit 和import AVFoundation。

每次点击 playerViewController 时，都会打印“touchesBegan”。
