在情节提要中更改 UIButton BorderColor [英] Change UIButton BorderColor in Storyboard

问题描述

我在用户定义的运行时属性中为 UIbutton 设置 CornerRadius 和 BorderWidth.在不添加 layer.borderColor 的情况下，它可以正常工作并以黑色显示边框.但是当添加 layer.borderColor 不起作用(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).

推荐答案

对于 Swift:

斯威夫特 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
        }
    }
}

斯威夫特 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
        }
    }
}
