如何接连播放AVPlayer视频？

import AVFoundation
import AVKit

class VideoPlayer {
    var player: AVQueuePlayer?
    var playerLayer: AVPlayerLayer?
    
    func playVideos(urls: [URL]) {
        var playerItems = [AVPlayerItem]()
        
        for url in urls {
            let playerItem = AVPlayerItem(url: url)
            playerItems.append(playerItem)
        }
        
        player = AVQueuePlayer(items: playerItems)
        playerLayer = AVPlayerLayer(player: player)
        
        // 设置视频播放器层的frame和其他属性
        playerLayer?.frame = CGRect(x: 0, y: 0, width: 320, height: 240)
        playerLayer?.videoGravity = .resizeAspect
        
        // 将视频播放器层添加到视图中
        if let playerLayer = playerLayer {
            view.layer.addSublayer(playerLayer)
        }
        
        // 监听播放完成通知
        NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: .AVPlayerItemDidPlayToEndTime, object: nil)
        
        // 开始播放视频
        player?.play()
    }
    
    @objc func playerDidFinishPlaying() {
        // 播放完成后的处理，可以在这里进行下一个视频的准备和播放操作
    }
}
