ios - 向 UILabel 添加填充

Question

我想以编程方式向 UILabel 中的文本添加左填充。我已经搜索了一个解决方案，但我无法在现有的 UILabel 扩展中工作。

class TopSideHeaderLabel: UILabel {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        adjustsFontSizeToFitWidth = true
        font = UIFont(name: Theme.PrimaryFontSemiBold, size: 16)
        textColor = Theme.White

        backgroundColor = Theme.background2
        textAlignment = .left
    }
}

使用插图怎么样？

class TopSideHeaderLabel: UILabel {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        adjustsFontSizeToFitWidth = true
        font = UIFont(name: Theme.PrimaryFontSemiBold, size: 16)
        textColor = Theme.White

        backgroundColor = Theme.background2
        textAlignment = .left
    }

    override func drawText(in rect: CGRect) {
        let insets = UIEdgeInsets.init(top: 10, left: 10, bottom: 10, right: 10)
        super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
    }
}
