学习记录

    @IBOutlet weak var imageView: UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        imageView.layer.shadowColor = UIColor.black.cgColor
        imageView.layer.shadowOffset = CGSize.init(width: 10, height: 10)  //偏移
        imageView.layer.shadowOpacity = 0.8  //透明度
        imageView.layer.shadowRadius = 10  //阴影半径
    }
