UILabel iOS Swift中的填充[重复]

Question

我已经从情节提要创建了一个标签，现在我正在尝试为该标签提供填充。我创建了一个类并尝试了以下两种方法，但没有任何效果。请帮忙。

override func drawTextInRect(rect: CGRect) {
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)))

    }


 let padding = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 10)


override func intrinsicContentSize() -> CGSize {
    let superContentSize = super.intrinsicContentSize()
    let width = superContentSize.width + padding.left + padding.right
    let heigth = superContentSize.height + padding.top + padding.bottom
    return CGSize(width: width, height: heigth)
}

Answer 1

试试这个，我已经用过，它从 SO 本身就可以工作

@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 drawTextInRect(rect: CGRect) {
        let insets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, insets))
    }

    override func intrinsicContentSize() -> CGSize {
        var intrinsicSuperViewContentSize = super.intrinsicContentSize()
        intrinsicSuperViewContentSize.height += topInset + bottomInset
        intrinsicSuperViewContentSize.width += leftInset + rightInset
        return intrinsicSuperViewContentSize
    }
}
