如何循环播放 AVQueuePlayer

Question

我有几个视频需要循环播放。

    let player = AVQueuePlayer(items: items)
    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame = view.bounds
    playerLayer.videoGravity = .resizeAspectFill
    view.layer.addSublayer(playerLayer)
    player.play()

我试图通过通知来实现，但我得到了正确的更新。

   NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: .main) {[weak self] (notification) in
        print("Notification: \(notification.object)")
    }

还尝试使用 PlayerLooper 但它正在循环播放单个项目。

    queuePlayer = AVQueuePlayer(items: items)
    playerLooper = AVPlayerLooper(player: queuePlayer!, templateItem: items[0])
    let playerLayer = AVPlayerLayer(player: queuePlayer!)
    playerLayer.frame = view.bounds
    playerLayer.videoGravity = .resizeAspectFill
    view.layer.addSublayer(playerLayer)
    queuePlayer?.play()
