iOS UIView subclass, draw see-through text to background

Question

I want to draw text onto my subclass on UIView so that the text is cut out of the shape and the background behind the view shows through, just like in the OSX Mavericks logo

Answer 1

If all you want is a white view with some stuff (text images, etc) cut out, then you can just do

yourView.layer.compositingFilter = "screenBlendMode"

This will leave the white parts white and the black parts will be see-through.
