How to draw border around a UILabel

Is there a way for UILabel to draw a border around itself  This is useful for me to debug the text placement and to see the placement and how big the label actually is

it really depends on how many boarder use in your view   sometimes   just add a UIVIEW which the size is a bit bigger to create the border   the method is faster than produce a view
