給UIButton擴展方法

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
    }
}

調(diào)用:

loginBtn.customBtn(customTitle: "登錄")
regisBtn.customBtn(customTitle: "注冊")

AVPlayerViewController的使用

實例化

let playerVC = AVPlayerViewController()

屬性和監(jiān)聽:

let url = URL(fileURLWithPath: Bundle.main.path(forResource: "moments", ofType: "mp4")!)
        playerVC.player = AVPlayer(url: url)//指定播放源
        playerVC.showsPlaybackControls = false//是否顯示工具欄
        playerVC.videoGravity = AVLayerVideoGravityResizeAspectFill//視頻畫面適應(yīng)方式
        playerVC.view.frame = YHRect
        playerVC.view.alpha = 0
        //監(jiān)聽視頻播放完的狀態(tài)
        NotificationCenter.default.addObserver(self, selector: #selector(repeatPlay), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerVC.player?.currentItem)
        view.addSubview(playerVC.view)
        view.sendSubview(toBack: playerVC.view)//放到最底層
        UIView.animate(withDuration: 1) {
            self.playerVC.view.alpha = 1;
            self.playerVC.player?.play()
        }

重復(fù)播放:

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