ios - 自定义 UILabel 类中的圆角半径

Question

我的 Storyboard 中有一个标签，我在其中使用以下代码对自定义类进行子类化

@IBDesignable class PaddingLabel: UILabel {

    @IBInspectable var topInset: CGFloat = 5.0
    @IBInspectable var bottomInset: CGFloat = 5.0
    @IBInspectable var leftInset: CGFloat = 7.0
    @IBInspectable var rightInset: CGFloat = 7.0

    override func drawText(in rect: CGRect) {
        let insets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
        super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
    }

    override var intrinsicContentSize: CGSize {
        var intrinsicSuperViewContentSize = super.intrinsicContentSize
        intrinsicSuperViewContentSize.height += topInset + bottomInset
        intrinsicSuperViewContentSize.width += leftInset + rightInset
        return intrinsicSuperViewContentSize
    }
}

我在我的自定义 TableviewCell awakeFromNib 函数中添加了 label?.layer.cornerRadius = 5。

它似乎没有影响标签。

添加 clipsToBounds 属性:

label?.clipsToBounds = true // or use label?.layer.masksToBounds = true
