Core Text and Uppercase Numbers

Core Text and upper case numbers is a decent article from Amy Worrall on how to deal with vertically aligning numeric glyphs in iOS. I've come across similar problems before with fonts on the web, but never considered it in terms of case before.

Anyway, Amy's solution uses TTTAttributedLabel to render her numbers using CoreText; I've used TTTAttributedLabel in projects before and highly recommend it.
