For some reason, when I try to animate textColor, it won't work. The textColor just suddenly changes from A to B. Is it possible to animate it, for example, red to black?
This answer is obsolete, and is not a good solution for the original question. @strange 's answer below is much better and should be used instead of this answer: https://stackoverflow.com/a/20892927/76559

The textColor property is not specified as being animatable in the docs, so I don't think you can do it with a simple UIView animations block...
This could probably be done pretty crudely with an NSTimer firing every couple of milliseconds, each time setting the colour gradually from one to the other.
I say this is crude because it would require an array or some other container of preset colour values going from the start colour to the finish colour, and I'm sure there's a way you could do this using core animation or something, I just don't know what it is.
