iOS Swift不能关闭avplayer模式

问题描述：

所以这里是我的使用案例 - 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以全屏模式播放视频。如果用户已登录并且未登录，用户可能会在两种不同的条件下观看视频。iOS Swift不能关闭avplayer模式

如果用户已登录（由变量值确定），则他可以观看完整的视频，否则，播放应在播放指定的秒数后停止（取决于视频中秒数的变化），并在播放器上出现横幅，要求其登录。

内联播放视频时，一切正常。但是，当视频播放全屏时，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，全屏模式并没有被解雇。代码片段是如下 -

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) 
}

我不知道这是否是正确的方法 -

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) 
       } 
      }

玩家控制器通过调用setupView功能，如下所示添加到视图做到这一点，有什么想法？

编辑：

接着按anbu.karthik的建议我试图通过定位顶视图控制器作为强行取出全屏视图：

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

，然后，用它作为如下 -

let currentTopVC: UIViewController? = self.currentTopViewController() 

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

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

和它的作品，但与下面的异常崩溃的应用程序 -

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>'

您没有删除'addPeriodicTimeObserver' –

答

据我所知，不可能直接播放全屏。看起来，AVPlayerViewController几乎是一样的，并没有提供很多定制UI或行为的方式。如果您想直接播放全屏，则需要以全屏模式呈现包含AVPlayerViewController的控制器，或者自行更改框架以使其全屏显示。但是没有API在AVPlayerViewController上以编程方式控制全屏...
