我必须在前一个视频中继的顶部画一个标签或按钮,留下评论.视频列表有它,一旦用户从表中选择一个项目,它需要播放,一旦播放器播放完成,那些按钮或标签应该出现在视频的顶部
这是我的代码：
comPlayerControl = AVPlayerViewController()
if let player = comPlayerControl {
let videoURL: String = "http://cdnapi.kaltura.com/p/11/sp/11/playManifest/entryId/"+selectedSubmission.transcodeRefId+"/format/applehttp/protocol/http/a.m3u8"
let playerItem = AVPlayerItem(URL: NSURL(string: videoURL)! )
commmentPlayer = AVPlayer(playerItem: playerItem)
player.player = commmentPlayer
player.view.frame = videoCell.frame
player.view.sizetoFit()
player.showsPlaybackControls = true
NSNotificationCenter.defaultCenter().addobserver(self,selector: #selector(CommentsTableViewController.playerDidFinishPlaying(_:)),name: AVPlayerItemDidplayToEndTimeNotification,object: playerItem)
comPlayerControl.delegate = self
videoCell.addSubview(player.view)
}
func playerDidFinishPlaying(note: NSNotification) {
print("Video Finished")
let DynamicView=UIView(frame: CGRectMake(100,200,100,100))
DynamicView.backgroundColor=UIColor.greenColor()
DynamicView.layer.cornerRadius=25
DynamicView.layer.borderWidth=2
DynamicView.layer.zPosition = 1;
comPlayerControl.view.addSubview(DynamicView)
}
像这样的要求
解决方法
您正在使用AVPlayerViewController,因此没有理由像Alessandro Ornano的回答那样访问您的应用程序窗口.为什么重新发明轮子？每个AVPlayerViewController都有一个
contentOverlayView属性,允许您在播放器和控件之间放置视图.
首先,创建一个新的AVPlayerItem并侦听该项目上的AVPlayerItemDidplayToEndTimeNotification通知.将项目加载到播放器中并开始播放.
项目完成后,将调用您指定用于侦听AVPlayerItemDidplayToEndTimeNotification通知的选择器.在该选择器中,直接访问contentOverlayView并添加按钮：
在某些视图控制器或其他对象中：
let playerVC = AVPlayerViewController()
// ...
func setupPlayer {
let playerItem = AVPlayerItem(...)
playerVC.player?.replaceCurrentItemWithPlayerItem(playerItem)
NSNotificationCenter.defaultCenter().addobserver(self,selector: #selector(VC.itemFinished),object: playerItem)
self.presentViewController(playerVC,animated: true) {
self.playerVC.player?.play()
}
}
func itemFinished() {
let btn = UIButton(type: .System)
btn.addTarget(self,action: #selector(VC.buttonTapped),forControlEvents: .TouchUpInside)
self.playerVC.contentOverlayView?.addSubview(btn)
}
func buttonTapped() {
print("button was tapped")
// replay/comment logic here
}
如注释(和rejected edit)中所述,按钮可能无法在contentOverlayView中使用.有关替代解决方案,请参阅Pyro’s answer.
您也可以将AVPlayerViewController子类化并在子类的实例中执行所有操作,但Apple warns against that：
Do not subclass
AVPlayerViewController. Overriding this class’s methods is unsupported and results in undefined behavior.
