无法从框架访问@IBInspectable属性

Question

我正在打包我每天在工作流程中使用的扩展。我在UIView上提取这个扩展并将其放入一个框架中。

我做了初始构建，所有这些IBInspectable属性在使用此框架的项目中都不可访问。下面是独立框架中的UIView扩展的代码。

public extension UIView {

    @IBInspectable public var cornerRadius: CGFloat {
        get {
            return self.layer.cornerRadius
        }

        set {
            self.layer.cornerRadius = newValue
        }
    }

    @IBInspectable public var borderWidth: CGFloat {
        get {
            return self.layer.borderWidth
        }

        set {
            self.layer.borderWidth = newValue
        }
    }

    @IBInspectable public var borderColor: UIColor? {
        get {
            guard let borderColor =  self.layer.borderColor else {
                return nil
            }
            return UIColor(cgColor: borderColor)
        }

        set {
            self.layer.borderColor = newValue?.cgColor
        }
    }

    @IBInspectable public var shadowColor: UIColor? {
        get {
            guard let shadowColor =  self.layer.shadowColor else {
                return nil
            }
            return UIColor(cgColor: shadowColor)
        }

        set {
            self.layer.shadowColor = newValue?.cgColor
        }
    }

    @IBInspectable public var shadowOffset: CGSize {
        get {
            return self.layer.shadowOffset
        }

        set {
            self.layer.shadowOffset = newValue
        }
    }

    @IBInspectable public var shadowRadius: CGFloat {
        get {
            return self.layer.shadowRadius
        }

        set {
            self.layer.shadowRadius = newValue
        }
    }

    @IBInspectable public var shadowOpacity: CGFloat {
        get {
            return CGFloat(self.layer.shadowOpacity)
        }

        set {
            self.layer.shadowOpacity = Float(newValue)
        }
    }
}

有没有想过，我可能做错了什么？

使用open而不是public作为访问说明符来访问模块外部的class和变量。

open extension UIView {

    @IBInspectable open var cornerRadius: CGFloat {
        get {
            return self.layer.cornerRadius
        }

        set {
            self.layer.cornerRadius = newValue
        }
    }
