Resizing a UILabel to accommodate insets

Question

I\'m building a screen to scan barcodes, and I need to put a translucent screen behind some UILabels to improve visibility against light backgrounds.

Here is an example of what I used for a simple 10 unit padding on the left and right of the label with rounded corners. Just set the label text to center it's self and make it's class IndentedLabel and the rest takes care of itself. To modify the padding just scale up or down rect.size.width += (x)

class IndentedLabel: UILabel {

    var edgeInsets:UIEdgeInsets = UIEdgeInsetsZero

    override func textRectForBounds(bounds: CGRect, limitedToNumberOfLines numberOfLines: Int) -> CGRect {
        var rect = super.textRectForBounds(UIEdgeInsetsInsetRect(bounds, edgeInsets), limitedToNumberOfLines: numberOfLines)

        rect.size.width  += 20;

        return rect
    }

    override func drawTextInRect(rect: CGRect) {
        self.clipsToBounds = true
        self.layer.cornerRadius = 3
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, edgeInsets))
    }
}
