快速介绍如何在AVPlayerViewController中播放视频时检测触摸 [英] In swift, how to detect touch while playing video in AVPlayerViewController

问题描述

我已通过编程方式将AVPlayerViewController添加到了UIViewController.播放器完成播放后，我可以收到通知(playerDidFinishPlaying).我还想知道在播放视频时用户是否触摸了屏幕，并且没有找到任何相关的通知.

I have programmatically added an AVPlayerViewController to a UIViewController. I am able to receive the notification when the player is finished playing (playerDidFinishPlaying). I would also like to know if a user has touched the screen while the video is playing and I have not found any related notifications.

解决方案是创建的 Base 类，并覆盖

The solution is to create a Base class of AVPlayerViewController and override touches​Began(_:​with:​) method:

迅速2:

自定义基础类:

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

ViewController:

ViewController:

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()
}

快捷键3:

自定义基础类:

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

View Controller:

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()
}

别忘了import AVKit和import AVFoundation.

每次点击playerViewController时，将打印"touchesBegan".

Each time you tap on the playerViewController, "touchesBegan" will be printed.
