To get the AVPlayerItemDidPlayToEndTimeNotificationyour object needs to be an AVPlayerItem.
要获得AVPlayerItemDidPlayToEndTimeNotification您的对象需要是一个AVPlayerItem.
To do so, just use the .currentItemproperty on your AVPlayer
为此，只需使用.currentItem您的财产AVPlayer
Now you will get a notification once the video ends!
现在，一旦视频结束，您将收到通知！
See my example:
看我的例子：
let videoPlayer = AVPlayer(URL: url)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerDidFinishPlaying:",
name: AVPlayerItemDidPlayToEndTimeNotification, object: videoPlayer.currentItem)
func playerDidFinishPlaying(note: NSNotification) {
print("Video Finished")
}
Swift 3

let videoPlayer = AVPlayer(URL: url)
NotificationCenter.default.addObserver(self, selector: Selector(("playerDidFinishPlaying:")),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: videoPlayer.currentItem)
func playerDidFinishPlaying(note: NSNotification) {
print("Video Finished")
}
Don't forget to remove the Observer in your deinit

This one works for me. Thanks to @Channel
这个对我有用。感谢@Channel
private func playVideo(fileURL: String) {
// Create RUL object
let url = URL(string: fileURL)
// Create Player Item object
let playerItem: AVPlayerItem = AVPlayerItem(url: url!)
// Assign Item to Player
let player = AVPlayer(playerItem: playerItem)
// Prepare AVPlayerViewController
let videoPlayer = AVPlayerViewController()
// Assign Video to AVPlayerViewController
videoPlayer.player = player
NotificationCenter.default.addObserver(self, selector: #selector(myViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: nil)
// Present the AVPlayerViewController
present(videoPlayer, animated: true, completion: {
// Play the Video
player.play()
})
}
@objc func finishVideo()
{
print("Video Finished")
}

For SWIFT 3.0This is working fine
对于 SWIFT 3.0这工作正常
class PlayVideoViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(PlayVideoViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTimeNotification, object: nil)
}
func finishVideo()
{
print("Video Finished")
}
}

I know there are a lot of accepted answers here...
我知道这里有很多公认的答案......
But, another route might be to add a boundary time observer to your AVPlayer. You would have to have the duration of the video, which you can get from your player.currentItem, and then add it as your desired time boundary.
但是，另一种方法可能是向您的 AVPlayer 添加一个边界时间观察器。您必须拥有视频的持续时间，您可以从您的 中获取player.currentItem，然后将其添加为您想要的时间边界。
fileprivate var videoEndObserver: Any?
func addVideoEndObserver() {
guard let player = YOUR_VIDEO_PLAYER else { return }
// This is just in case you are loading a video from a URL.
guard let duration = player.currentItem?.duration, duration.value != 0 else {
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: { [weak self] in
self?.addVideoEndObserver()
})
return
}
let endTime = NSValue(time: duration - CMTimeMakeWithSeconds(0.1, duration.timescale))
videoEndObserver = player.addBoundaryTimeObserver(forTimes: [endTime], queue: .main, using: {
self.removeVideoEndObserver()
// DO YOUR STUFF HERE...
})
}
func removeVideoEndObserver() {
guard let observer = videoEndObserver else { return }
videoPlayer.player?.removeTimeObserver(observer)
videoEndObserver = nil
}

It's really this simple
真的这么简单
NotificationCenter.default.addObserver(
self,
selector: #selector(fileComplete),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: nil)
(It's fine for the object to be nil.)
（对象为零也可以。）
and then
进而
@objc func fileComplete() {
print("IT'S DONE!")
}

In Swift 3 and RxSwift 3.5 all you have to do is:
在 Swift 3 和 RxSwift 3.5 中，你所要做的就是：
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.rx.notification(Notification.Name.AVPlayerItemDidPlayToEndTime)
.asObservable().subscribe(onNext: { [weak self] notification in
//Your action
}).addDisposableTo(disposeBag)
}

Here 'fullUrl' is the URL of the video and make sure that there would be no space in the URL, You should replace 'Space' with '%20' so that URL will work file.
这里'fullUrl'是视频的URL，确保URL中没有空格，你应该用'%20'替换'Space'，这样URL就可以工作文件。
let videoURL = NSURL(string: fullUrl)
let player = AVPlayer(url: videoURL! as URL)
playerViewController.delegate = self
playerViewController.player = player
self.present(playerViewController, animated: false) {
self.playerViewController.player!.play()
NotificationCenter.default.addObserver(self, selector: #selector(yourViewControllerName.playerDidFinishPlaying), name: Notification.Name.AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem)
}
Add this below given method in your view controller.
在您的视图控制器中添加下面给定的方法。
func playerDidFinishPlaying(){
print("Video Finished playing in style")
}
