Animate UILabel text between two numbers?

I'm new to iPhone and Mac programming (developed for Windows before), and I've got a question:

How do I animate the text property of an UILabel between two numbers, e.g. from 5 to 80 in an Ease-Out style? Is it possible with CoreAnimation? I have been searching on Google for an hour, but I haven't found anything solving my problem. What I want: Animate the users money for a simple game. It doesn't look very nice when it just goes from 50 to 100 or something like that without animation.

Anyone having an idea how to do that?

Thanks!
