If you want to animate between different title strings, use the following:

CATransition *fadeTextAnimation = [CATransition animation];
fadeTextAnimation.duration = 0.5;
fadeTextAnimation.type = kCATransitionFade;

[self.navigationController.navigationBar.layer addAnimation: fadeTextAnimation forKey: @"fadeText"];
self.navigationItem.title = "My new title";

You can adjust the duration and set a timing function to suit, of course.

There are also other types of animation that might work in different circumstances (thanks @inorganik):

kCATransitionFade
kCATransitionMoveIn
kCATransitionPush
kCATransitionReveal
