How to animate the background color of a UILabel?

I'm pretty new to animating things on iOS and have a basic question.

I have a UILabel that I want to briefly change the color of. Basically, inside of cellForRowAtIndexPath: I am reloading my cell's every 15 seconds or so. If a certain cell meet's a requirement, I want to briefly change the label's color and animate it to fade off back to it's original color.

Pop on, fade out.

Any tips would be amazing. Thanks guys.

Bum deal. I guess I'll have to find another solution. Thanks Totumus. — crewshin, Oct 15 '11 at 18:42
You might wanna try the NSTimer thing with 2 labels on top of eachother. You will figure it out ;) Its in the same question if i recall. — Totumus Maximus, Oct 15 '11 at 20:00

This isn't the brightest solution, but it might get you to what you need: Create an identical, new UILabel with the same frame, font, etc... but with a different color. Use the animatable "alpha" property to fade your old color out and it will seem as if the underlaying label's color is being transitioned in.

Actually, this is a pretty good solution. Since we're not redrawing the label - just changing the alpha - it's going to be *fast* (much faster than a re-implementation of UILabel that actually redraws the text in a new colour). – Nuoji May 15 '13 at 22:24
