ios - 为 UIView 添加阴影和角，除了底部

Question

我想在左上角和右上角添加圆角，并在其周围添加阴影(底部除外)。底部不应有阴影。我能够根据需要实现圆角。但不是影子。我需要一个同时实现两者的代码。在下图中查看诊断 View 。它的左上角和右上角是圆形的，周围有阴影。

Answer 1

试试这个代码。自定义方法。 swift 4.0

@IBOutlet weak var myView: UIView!
override func viewDidLoad() {
    super.viewDidLoad()
    customCornerWithShadow(myView: myView, cornerRadius: 20)
}

func customCornerWithShadow(myView:UIView,cornerRadius:CGFloat) {

    myView.layer.cornerRadius = cornerRadius
    myView.clipsToBounds = false[enter image description here][1]
    myView.layer.maskedCorners = CACornerMask(rawValue: CACornerMask.RawValue(UInt8(CACornerMask.layerMinXMinYCorner.rawValue) | UInt8(CACornerMask.layerMaxXMinYCorner.rawValue)))

    myView.layer.shadowColor = #colorLiteral(red: 0.3098039329, green: 0.01568627544, blue: 0.1294117719, alpha: 1)
    myView.layer.shadowOffset = CGSize(width:0, height:-1)

    let shadowPath = UIBezierPath(roundedRect: myView.bounds, cornerRadius: cornerRadius)
    myView.layer.shadowPath = shadowPath.cgPath
    myView.layer.shadowOpacity = 1
}
