Ios 播放结束后无法重放视频

我使用以下代码显示两个不同的视频源作为背景。“selectVideo”（

SegmentedControl

）用于选择视频。问题就在下面

@IBAction func selectVideo(sender: AnyObject) {
    if self.Controller.selectedIndex == 1 {
        self.videoBackgroundCustomer()
    }

    if self.Controller.selectedIndex == 0 {
        self.videoBackgroundDriver()
    }
}

    func videoBackgroundDriver() {
        //Load video background.
        let videoURL: NSURL = NSBundle.mainBundle().URLForResource("background_video_2", withExtension: "mp4")!

        player = AVPlayer(URL: videoURL)
        videoBackground()
    }

    //Video background customer
    func videoBackgroundCustomer() {
        //Load video background.
        let videoURL: NSURL = NSBundle.mainBundle().URLForResource("background_video_1", withExtension: "mp4")!

        player = AVPlayer(URL: videoURL)
        videoBackground()
    }

    //Vieobackground-code part 2, provides with less code.
    func videoBackground() {
        player?.actionAtItemEnd = .None
        player?.muted = true

        let playerLayer = AVPlayerLayer(player: player)
        playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
        playerLayer.zPosition = -1

        playerLayer.frame = view.frame

        view.layer.addSublayer(playerLayer)

        player?.play()

        //call loop video
        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(LoginViewController.loopVideo), name: AVPlayerItemDidPlayToEndTimeNotification, object: player!.currentItem)
    }

    //Loop video
    func loopVideo() {
        player?.seekToTime(kCMTimeZero)
        player?.play()
    }

问题：上次视频本应结束时，视频将重新启动。而不是在最近的视频结束时。

如何在上次播放视频结束后使其重复播放？感谢

在对问题进行调查之后，首先查看并返回该方法的值

- (void)seekToTime:(CMTime)time;

方法，您正在使用return

void

，无法与

CMTime

要解决您的问题，请尝试以下解决方案：

首先，您需要向您的班级订阅通知，该通知将指示视频结束

NSNotificationCenter.defaultCenter().addObserver(self,selector: "itemDidReachEnd:",
    name: AVPlayerItemDidPlayToEndTimeNotification,
    object: player.currentItem)

然后定义处理此通知的方法

func itemDidReachEnd(notification: NSNotification) {
    player.seekToTime(kCMTimeZero)
    player.play()
}

---

在本例中，您正在跟踪视频何时结束并重新开始。

方法

seekToTime

的返回类型是

void

而不是

CMTime

。不知何故，我现在又遇到了一个bug，我已经更新了这个问题。谢谢
