TableFlip is an open source library from Joe Fabisevich that makes animating UITableViews simple allowing you to create table animations with a few lines using some great built-in animations or custom animations with CGAffineTransform.
With TableFlip you can apply animations to the tableview at once or to each cell individually, and built-in are animations from the top or sides, and fade animations. Duration of the animations can also be controlled. Several examples are in the readme.
Here is a staggered from the left animation from the readme:

A nice library for animating table views.
