ios - Swift Youtube 播放器内存泄漏

Question

我正在使用 Swift-YouTube-Player 库。这是一个 link !

我在 tableview 中列出视频。我的问题是内存问题。我知道我应该在加载选定的 videoPlayer 之前清除所有 videoPlayer.clean()。

我的问题是如何在加载另一个视频之前清除应用中播放器的每个实例。

我的代码是这样的:

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

        if let jlist = self.searchedJoinAllAllowedInnoList , !jlist.isEmpty{

            let cell = tableView.dequeueReusableCell(withIdentifier: "JoinCell", for: indexPath) as! JoinCell
            cell.delegate = self
            cell.indexPath = indexPath
            //--
            cell.videoName.text = jlist[indexPath.row].shortDesc
            cell.EndDate.text = getDate(unixdate: jlist[indexPath.row].joinEnd!, timezone: "UTC")
            if let videoKey = jlist[indexPath.row].teaserVideo , !videoKey.isEmpty{
                print("video key:\(videoKey)")
                cell.thubnailImageView.sd_setImage(with: URL(string: "https://img.youtube.com/vi/\(videoKey)/hqdefault.jpg"), placeholderImage: UIImage(named: "lcw"))
                let playerVars = ["controls": "1", "playsinline": "1", "autohide": "1", "showinfo": "1", "autoplay": "0", "fs": "1", "rel": "0", "loop": "0", "enablejsapi": "1", "modestbranding": "1"]
                cell.videoPlayer.playerVars = playerVars as YouTubePlayerView.YouTubePlayerParameters
                cell.videoPlayer.clear()
            }

            return cell
        }
        else {
            let cell = UITableViewCell()
            cell.selectionStyle = .none
            cell.backgroundColor = .clear
            cell.textLabel?.textAlignment = .center
            cell.textLabel?.textColor = UIColor.black
            cell.textLabel?.text = "nodataavaiable".localized()
            return cell
        }
    }

我的自定义播放按钮代表是:

extension JoinViewController : JoinCellButtonsDelegate {


    func playButtonDelegate(at index: IndexPath) {
        if let jlist = self.searchedJoinAllAllowedInnoList , !jlist.isEmpty{
            if let videoKey = jlist[index.row].teaserVideo , !videoKey.isEmpty{
                let cell = joinTableView.cellForRow(at: index) as! JoinCell

                cell.videoPlayer.clear()
                cell.videoPlayer.loadVideoID(videoKey)
                    cell.videoPlayer.play()
                    self.delayWithSeconds(2, completion: {
                        cell.videoPlayer.play()
                        cell.thubnailView.isHidden = true
                    })

            }
        }
    }
 }

Answer 1

我不确定，但我可以尝试在最后一个闭包中使用弱单元格引用。

delayWithSeconds(2, completion: { [weak cell] in
     cell?.videoPlayer.play()
     cell?.thubnailView.isHidden = true
})

并且不要忘记删除上一行:cell.videoPlayer.play()。
