你可以这样尝试。

  if #available(iOS 11.0, *) {
        customView.layer.cornerRadius = 10
        customView.layer.maskedCorners = [.layerMinXMaxYCorner,.layerMinXMinYCorner,.layerMaxXMinYCorner]
    } else {
       // Fallback on earlier versions

        let rectShape = CAShapeLayer()
        rectShape.bounds = customView.frame
        rectShape.position = customView.center
        rectShape.path = UIBezierPath(roundedRect: customView.bounds,    byRoundingCorners: [.bottomRight , .topLeft , .topRight], cornerRadii: CGSize(width: 10, height: 10)).cgPath
        customView.layer.mask = rectShape
  }
