Question

我曾经使用avplayer在UITableViewCell上加载视频。我可以在UITableViewCell上加载视频，但我无法暂停/播放视频。我不能做任何基本功能，如增加/减少音量。请任何人帮我解决这个问题。这是我的代码：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
    {

        let cell: FeedCell = tableView.dequeueReusableCell(withIdentifier: "VedioCell", for: indexPath) as! FeedCell

        let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
          player = AVPlayer(url: videoURL! as URL)
        let playerLayer = AVPlayerLayer(player: player)

        playerLayer.frame = CGRect(x:0, y: 0, width: UIScreen.main.bounds.width, height: 200)
       cell.PlayerView?.layer.addSublayer(playerLayer)
          player.play()

    return cell
    }

我在这里使用了avplayer，但我无法访问

先谢谢。

试试这个

func tableView（_ tableView：UITableView，cellForRowAt indexPath：IndexPath） - ＆gt;的UITableViewCell {

        let cell: FeedCell = tableView.dequeueReusableCell(withIdentifier: "VedioCell", for: indexPath) as! FeedCell

        let player = playerArray[indexPath.row]
        let playerLayer = AVPlayerLayer(player: player)
        playerLayer.frame = CGRect(x:0, y: 0, width: UIScreen.main.bounds.width, height: 200)
       cell.PlayerView?.layer.addSublayer(playerLayer)

        cell.play.tag = indexPath.row

        cell.play.addTarget(self, action: #selector(GetUpdatesButtonTouched), for: .touchUpInside)


               return cell
    }


 @IBAction func GetUpdatesButtonTouched(_ sender: AnyObject) {

        if sender.currentTitle == "Play" {
            for i in 0..<10{
                currentPlayer=playerArray[i]
                currentPlayer.pause()
                print("tag: \(sender.tag)")
                print("tag: \(playerArray)")
                currentPlayer=playerArray[sender.tag]
                print("tag: \(currentPlayer)")
                //  handleVideoChageSlider(("" as AnyObject) as! UISlider)
                currentPlayer.play()

                sender.setTitle("Pause", for: UIControlState.normal)

              //  let indexPath = tableView.indexPathForSelectedRow!
               let cell: FeedCell = tableView.cellForRow(at:sender.indexPath)as! FeedCell

                //print(currentCell.videoLabel.text)

                //cell.slider.tag=indexPath.row
                cell.slider.addTarget(self, action: #selector(handleVideoChageSlider), for:.valueChanged )

            }
        }
        else if sender.currentTitle == "Pause"{
            for i in 0..<10{
                currentPlayer=playerArray[i]
                currentPlayer.pause()
                sender.setTitle("Play", for: UIControlState.normal)
            }
        }
    }

Answer 2

尝试这种方法：

1）在AVPlayer班级中声明cell的变量。

2）在cellWillAppear内，实例化此变量，如

cell.avplayer = AVPlayer(url: videoURL! as URL)

3）在cellWillDisapper内，制作avplayer nil

cell.avplayer = nil

4）要增加/减少音量，请仅使用该特定avplayer的{{1}}。

Answer 3

也许您应该重复使用AVPlayerLayer，或者“https”导致它

我不能暂停在桌面上播放视频
