在WebView中播放视频时，在iOS (Swift)中将UIButton添加到AVPlayer

import AVKit

let playerViewController = AVPlayerViewController()
addChild(playerViewController)
view.addSubview(playerViewController.view)
playerViewController.view.frame = view.bounds

import AVFoundation

let videoURL = URL(string: "视频的URL")
let player = AVPlayer(url: videoURL!)

playerViewController.player = player

let button = UIButton(type: .system)
button.setTitle("播放/暂停", for: .normal)
button.addTarget(self, action: #selector(playPauseButtonTapped), for: .touchUpInside)

@objc func playPauseButtonTapped() {
    if player.timeControlStatus == .playing {
        player.pause()
    } else {
        player.play()
    }
}

playerViewController.contentOverlayView?.addSubview(button)
button.frame = CGRect(x: 20, y: 20, width: 100, height: 40)
