swift：设置部分圆角

可以将下面的configRectCorner方法写成公共方法，方便调用

let label = UILabel(frame: CGRect(x: 50, y: 100, width: 100, height: 50))
label.backgroundColor = UIColor.orange
label.textColor = UIColor.white
label.text = "圆角设置"
label.textAlignment = .center
        
label.layer.mask = self.configRectCorner(view: label, corner: [.topRight, .bottomRight], radii: CGSize(width: 15, height: 15))
        
 self.view.addSubview(label)
    
    /// 圆角设置
    ///
    /// - Parameters:
    ///   - view: 需要设置的控件
    ///   - corner: 哪些圆角
    ///   - radii: 圆角半径
    /// - Returns: layer图层
    func configRectCorner(view: UIView, corner: UIRectCorner, radii: CGSize) -> CALayer {
        
        let maskPath = UIBezierPath.init(roundedRect: view.bounds, byRoundingCorners: corner, cornerRadii: radii)
        
        let maskLayer = CAShapeLayer.init()
        maskLayer.frame = view.bounds
        maskLayer.path = maskPath.cgPath
        
        return maskLayer
    }
