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 a Swift version of a UILabel subclass (same as @Nikolai's answer) that creates an additional padding around the text of a UILabel:

class EdgeInsetLabel : UILabel {
    var edgeInsets:UIEdgeInsets = UIEdgeInsetsZero

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

        rect.origin.x -= edgeInsets.left
        rect.origin.y -= edgeInsets.top
        rect.size.width  += (edgeInsets.left + edgeInsets.right);
        rect.size.height += (edgeInsets.top + edgeInsets.bottom);

        return rect
    }

    override func drawTextInRect(rect: CGRect) {
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, edgeInsets))
    }
}
