Here’s a library called FastAnimationWithPOP from William Zang that makes creating animations with Pop easier through attributes so you can create different animations without code in Storyboards (you can also create animations easily using code if desired).

FastAnimationWithPop provides attributes for controlling the animation details, delay, duration, and more, makes it easy to extend animations, allows animations to automatically run when awaken from a nib, and more. A demonstration app is included.

Here’s an image from the readme showing off a few animations in the demo:

A nice easy to use animation framework.
