iOS Swift无法解雇avplayer模态

所以这是我的用例 - 我们正在使用avplayer加载视频并播放它，用户可以点击默认的全屏按钮来全屏播放视频 . 用户可能正在以两种不同的条件观看视频，如果他已登录并且他未登录 .

如果用户已登录（由变量值确定），则可以观看完整视频，否则播放应在播放定义的秒数后停止（取决于视频的秒数变化），并且会出现 Banner 在玩家要求他登录 .

视频正在内联播放时，一切正常 . 但是，当视频正在全屏播放时，即使我们使用 didTapPause() 停止播放，全屏窗口也不会被解除 . 我甚至尝试使用 self.playerController.dismiss(animated: true, completion: nil) 解雇它，全屏模式不会被解雇 . 它的代码片段如下 -

playerController.player?.addPeriodicTimeObserver(forInterval: CMTimeMakeWithSeconds(1, 1), queue: DispatchQueue.main) { (CMTime) -> Void in
        if self.playerController.player?.currentItem?.status == .readyToPlay {
            self.videoCurrentTimeDuration = CMTimeGetSeconds((self.playerController.player?.currentItem!.currentTime())!);
            self.videoTimeDuration = CMTimeGetSeconds((self.playerController.player?.currentItem?.duration)!);



            if self.moveToTime != nil{
                let timeWithSecond = CMTimeMakeWithSeconds(self.videoTimeDuration! * self.moveToTime! / 100, Int32(kCMTimeMaxTimescale))

                self.playerController.player?.seek(to: timeWithSecond, toleranceBefore: kCMTimeZero, toleranceAfter: kCMTimeZero)
                self.moveToTime = nil
            }

            guard let videoD = self.videoData else { return }

            let timeTToPlay: Double = Double(videoD.freeDuration)

            if videoD.isFree {
                if videoD.registrationNeeded && !CurrentLoginUser.shared.isLogin{
                    if self.videoCurrentTimeDuration! > timeTToPlay {
                        self.didTapPause()

                        self.playerController.dismiss(animated: true, completion: nil)


                        self.loginNeedView = UINib.get(withNib: self)
                        self.loginNeedView?.frame = self.bounds

                        self.loginNeedView?.autoresizingMask = [
                            UIViewAutoresizing.flexibleWidth,
                            UIViewAutoresizing.flexibleHeight
                        ]
                        self.addSubview(self.loginNeedView!)
                        AppUtility.lockOrientation(UIInterfaceOrientationMask.portrait, andRotateTo: UIInterfaceOrientation.portrait)
                    }
                }
                else{
                    self.loginNeedView?.removeFromSuperview()
                    AppUtility.lockOrientation(UIInterfaceOrientationMask.all)
                }
            }

通过调用 setupView 函数将播放器控制器添加到视图中，如下所示 -

private func setUpView() {
    self.backgroundColor = .black
    addVideoPlayerView()
    configurateControls()
}

fileprivate func addVideoPlayerView() {
    playerController.view.frame = self.bounds
    playerController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    playerController.showsPlaybackControls = true
    playerController.addObserver(self, forKeyPath: "videoBounds", options: NSKeyValueObservingOptions.new, context: nil)
    self.insertSubview(playerController.view, at: 0)
}

我不确定这是否是正确的方法，任何想法？

编辑：

接下来按照anbu.karthik的建议，我试图通过将顶视图控制器定位为强制删除全屏视图：

func currentTopViewController() -> UIViewController {
var topVC: UIViewController? = UIApplication.shared.delegate?.window??.rootViewController
while ((topVC?.presentedViewController) != nil) {
topVC = topVC?.presentedViewController
}
return topVC! 
}

然后，用它如下 -

let currentTopVC: UIViewController? = self.currentTopViewController()

                        if (currentTopVC?.description.contains("AVFullScreenViewController"))! {
                            print("found it")

                            currentTopVC?.dismiss(animated: true) { _ in }
                        }

它可以工作，但崩溃的应用程序有以下例外 -

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<AVEmbeddedPlaybackControlsViewController: 0x7fdcc2264400> should have parent view controller:<AVPlayerViewController: 0x7fdcc222a800> but actual parent is:<AVFullScreenViewController: 0x7fdcce2f3c50>'
