class UILabelOverride: UILabel {        override func textRectForBounds(bounds: CGRect, limitedToNumberOfLines numberOfLines: Int) -> CGRect {        var rect = super.textRectForBounds(bounds, limitedToNumberOfLines: numberOfLines)        rect.origin.x = CGFloat(10)        return rect    }    override func drawTextInRect(rect: CGRect) {        let aRect = self.textRectForBounds(rect, limitedToNumberOfLines: self.numberOfLines)        super.drawTextInRect(aRect)            }}

 重写这两个方法之后就可以实现
