   func roundCorners(corners:UIRectCorner, radius: CGFloat) {
       let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
       let mask = CAShapeLayer()
       mask.path = path.cgPath
       self.layer.mask = mask
   }

3. 覆盖draw(_:):

   func draw(_ rect: CGRect) {
       // Size of rounded rectangle
       let rectWidth = rect.width
       let rectHeight = rect.height
   
       // Find center of actual frame to set rectangle in middle
       let xf: CGFloat = (self.frame.width …
