无需用户交互即可在iOS上一个接一个地播放视频

import AVFoundation

let player = AVPlayer()

let videoURLs = ["video1.mp4", "video2.mp4", "video3.mp4"] // 视频文件的URL数组
var currentItemIndex = 0 // 当前播放的视频索引

func createPlayerItem() -> AVPlayerItem? {
    guard currentItemIndex < videoURLs.count else {
        return nil // 所有视频已经播放完毕
    }
    
    let videoURL = URL(fileURLWithPath: videoURLs[currentItemIndex])
    let playerItem = AVPlayerItem(url: videoURL)
    currentItemIndex += 1
    
    return playerItem
}

NotificationCenter.default.addObserver(self, selector: #selector(playerItemDidReachEnd), name: .AVPlayerItemDidPlayToEndTime, object: nil)

@objc func playerItemDidReachEnd() {
    guard let playerItem = createPlayerItem() else {
        return // 所有视频已经播放完毕
    }
    
    player.replaceCurrentItem(with: playerItem)
    player.play()
}
