Swift - 全屏时 ControlContainerView 从 VideoPlayerView 中消失

Question

我实现了一个本地视频播放器，它支持非全屏和全屏模式，在 videoPlayerView 的右下角有一个切换全屏按钮。我添加了一个名为controlsContainerView 的 subview ，其中包括播放/暂停按钮、 slider 、两个标签以及切换全屏按钮。我还添加了一个 tapGesture 识别器来让用户在 videoPlayerView 上点击手势，以便处理天气或不显示controlsContainerView。我的问题来了:

在非全屏模式下，一切正常。单击切换全屏按钮后，videoPlayerView 会在视频播放时旋转 90 度并扩展到全屏。但是，无论我是否点击屏幕，控件容器 View 都会消失。我打印出controlsContainerView 的isHidden 状态，它在“true”和“false”之间变化，这是应该的。框架的大小和位置也很好。但它不会在视觉上显示出来。

func handleFullScreen() {
    controlsContainerView.removeFromSuperview()
    if isFullScreen {
        fullScreenBtn.setImage(UIImage(named: "full_screen"), for: .normal)
        UIView.animate(withDuration: 3, animations: {
            let width = UIApplication.shared.keyWindow?.frame.width
            let height = width!*9/16
            self.transform = CGAffineTransform(rotationAngle: 0)
            self.frame = CGRect(x: 0, y: 0, width: width!, height: height)
        })
    } else {
        fullScreenBtn.setImage(UIImage(named: "full_screen_exit"), for: .normal)
        UIView.animate(withDuration: 3, animations: {

            self.transform = CGAffineTransform(rotationAngle: CGFloat.pi/2)
            self.frame = UIScreen.main.bounds
            self.controlsContainerView.frame = self.bounds
            self.playerLayer.frame = self.bounds
        })

    }
    isFullScreen = !isFullScreen
}

func handleControlsContainerViewHide() {
    print("Tapped")
    if controlsContainerViewIsHidden {
        controlsContainerView.isHidden = false
    } else {
        controlsContainerView.isHidden = true
    }
    controlsContainerViewIsHidden = !controlsContainerViewIsHidden
    print(controlsContainerView.isHidden)
}

func setupVideoControlView() {
    //setupGradientLayer()

    self.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleControlsContainerViewHide)))
    controlsContainerView.frame = bounds

    addSubview(controlsContainerView)
// Sub views of controls container view, I deleted the layout constraints since they are irrelevant to this question.

    controlsContainerView.addSubview(activityIndicatorView)

    controlsContainerView.addSubview(pausePlayBtn)

    controlsContainerView.addSubview(fullScreenBtn)

    controlsContainerView.addSubview(videoLengthLabel)

    controlsContainerView.addSubview(currentTimeLabel)

    controlsContainerView.addSubview(videoSlider)

    controlsContainerView.addSubview(closeBtn)

}

感谢您阅读我的问题，希望您能给我一些见解!

对不起，我傻了。我自己手动删除了controlsContainerView，这正是它没有显示的原因。
