问题描述

我在用户定义的运行时属性中为UIbutton设置CornerRadius和BorderWidth。没有添加 layer.borderColor ,它可以很好地显示黑色的边框。但是,当添加 layer.borderColor 不起作用时(不显示边框)。

I Set CornerRadius and BorderWidth for UIbutton in User Defined Runtime Attributes. Without adding layer.borderColor it works Well and Display border in black color. But when add layer.borderColor does not work(does not show border).

感谢提前。

推荐答案

对于Swift:

Swift 3:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(cgColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.cgColor
        }
    }
}

Swift 2.2: p>

Swift 2.2:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(CGColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.CGColor
        }
    }
}
