我在我的容器视图中嵌入了一个 UITableView，它在当前上下文中以模态方式呈现。视频加载正常，但我无法简单地关闭视频并返回我的 UITableView。我希望视频的选项能够关闭并简单地返回到原始的 tableView。

表视图 视频加载

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()

  }

}

我最终添加了一个关闭按钮并将其限制在我的 containerView 的右上角，并在视频关闭后将其设置为隐藏。

  @objc func dismissVideo() {
    self.playerView.removeFromSuperview()
    closeButton.isHidden = true

}


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)
    closeButton.addTarget(self, action: #selector(dismissVideo), for: .touchUpInside)
    closeButton.isHidden = false
}
