IBDesignable构建失败 [英] IBDesignable Build Failed

问题描述

我已经创建了IBDesignable和IBInspectable自定义类，以提供视图的阴影和拐角半径

I have Created IBDesignable and IBInspectable custom class to give shadow and corner radius for view

但是当我将Designable类分配给view时，我得到了Designable Build Failed

But When I assign Designable class to view, I get Designable Build Failed

这是我的代码

import Foundation

import UIKit

@IBDesignable
class DesignableView: UIView {
}

@IBDesignable
class DesignableButton: UIButton {
}

@IBDesignable
class DesignableLabel: UILabel {
}

@IBDesignable
class DesignableTableView: UITableView {

}

extension UIView {

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

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

    @IBInspectable
    var borderColor: UIColor? {
        get {
            if let color = layer.borderColor {
                return UIColor(cgColor: color)
            }
            return nil
        }
        set {
            if let color = newValue {
                layer.borderColor = color.cgColor
            } else {
                layer.borderColor = nil
            }
        }
    }

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

    @IBInspectable
    var shadowOpacity: Float {
        get {
            return layer.shadowOpacity
        }
        set {
            layer.shadowOpacity = newValue
        }
    }

    @IBInspectable
    var shadowOffset: CGSize {
        get {
            return layer.shadowOffset
        }
        set {
            layer.shadowOffset = newValue
        }
    }

    @IBInspectable
    var shadowColor: UIColor? {
        get {
            if let color = layer.shadowColor {
                return UIColor(cgColor: color)
            }
            return nil
        }
        set {
            if let color = newValue {
                layer.shadowColor = color.cgColor
            } else {
                layer.shadowColor = nil
            }
        }
    }
}

这就是我得到的

推荐答案

失败了，因为IBInspectable的变量用于其他人的IBDesignable类

It was failing because the variables of IBInspectable are used in someone else's IBDesignable class

以下步骤解决了该问题:

The following steps resolved the issue:

1. 重命名课程
2. 清理项目.
3. 选择情节提要，转到编辑器"菜单，然后执行刷新所有视图"，或者选择自动刷新"视图；等待构建完成.
