给UIButton扩展方法

extension UIButton {
    func customBtn(customTitle title: String) {
        setTitle(title, for: .normal)
        setTitleColor(.white, for: .normal)
        layer.cornerRadius = 5.0
        layer.borderColor = UIColor.white.cgColor
        layer.borderWidth = 1.0
    }
}

调用:

loginBtn.customBtn(customTitle: "登录")
regisBtn.customBtn(customTitle: "注册")

AVPlayerViewController的使用

实例化

let playerVC = AVPlayerViewController()

属性和监听:

let url = URL(fileURLWithPath: Bundle.main.path(forResource: "moments", ofType: "mp4")!)
        playerVC.player = AVPlayer(url: url)//指定播放源
        playerVC.showsPlaybackControls = false//是否显示工具栏
        playerVC.videoGravity = AVLayerVideoGravityResizeAspectFill//视频画面适应方式
        playerVC.view.frame = YHRect
        playerVC.view.alpha = 0
        //监听视频播放完的状态
        NotificationCenter.default.addObserver(self, selector: #selector(repeatPlay), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerVC.player?.currentItem)
        view.addSubview(playerVC.view)
        view.sendSubview(toBack: playerVC.view)//放到最底层
        UIView.animate(withDuration: 1) {
            self.playerVC.view.alpha = 1;
            self.playerVC.player?.play()
        }

重复播放:

playerVC.player?.seek(to: kCMTimeZero)
playerVC.player?.play()
