ios - YTPlayerView() を閉じて UITableView に戻る

Question

現在のコンテキストでモーダルに表示されているコンテナー ビュー内に UITableView が埋め込まれています。ビデオは正常に読み込まれますが、単純にビデオを閉じて UITableView に戻る方法はありません。ビデオを閉じて、元の tableView に戻ることができるようにするオプションが欲しいです。

class MotivationViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, YTPlayerViewDelegate {

  override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(playerView)
    playerView.delegate = self

    search()
    self.tableView.delegate = self
    self.tableView.dataSource = self
    print(dataArray)
    tableView.register(YouTubeTableCell.self, forCellReuseIdentifier: cellID)
    view.addSubview(containerView)
    view.addSubview(titleLabel)

    containerView.anchor(top: view.topAnchor, left: view.leftAnchor, bottom: view.bottomAnchor, right: view.rightAnchor, paddingTop: 200, paddingLeft: 20, paddingBottom: 200, paddingRight: 20, width: 0, height: 0)

    containerView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    containerView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

    containerView.addSubview(tableView)
    tableView.translatesAutoresizingMaskIntoConstraints = false
    tableView.layer.cornerRadius = 20
    tableView.anchor(top: containerView.topAnchor, left:         containerView.leftAnchor, bottom: containerView.bottomAnchor, right: containerView.rightAnchor, paddingTop: 0, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 0, height: 0)
    titleLabel.anchor(top: nil, left: nil, bottom: containerView.topAnchor, right: nil, paddingTop: 0, paddingLeft: 0, paddingBottom: 10, paddingRight: 0, width: 0, height: 0)
    titleLabel.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
  }

  func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: cellID, for: indexPath) as! YouTubeTableCell

    let item = titlesArray[indexPath.row]
    cell.titleLabel.text = item
    let imageURL = URL(string: thumbnailArray[indexPath.row])
    cell.thumbnailImageView.sd_setImage(with: imageURL)
    return cell
  }

  func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let item = videoID[indexPath.row]
    view.addSubview(playerView)
    playerView.layer.cornerRadius = 20
    playerView.anchor(top: containerView.topAnchor, left: containerView.leftAnchor, bottom: containerView.bottomAnchor, right: containerView.rightAnchor, paddingTop: 0, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 0, height: 0)
    let playerVars = ["playsinline": 1] // 0: will play video in fullscreen
    self.playerView.load(withVideoId: item, playerVars: playerVars)
  }

func dismiss() {

    self.playerView.removeFromSuperview()

  }

}
