How can I implement an animated intro screen as IFTTT's?

Question

I saw how awesome IFTTT's intro screen is and I also want to implement something that awesome in my app. How can I do it?

Answer 1

Actually, IFTTT has open sourced the framework they created for this. It's called JazzHands and it's available on GitHub:

Jazz Hands is a simple, keyframe based animation framework for UIKit. Animations can be controlled via gestures, scroll views, kvo, or ReactiveCocoa.

Jazz Hands is used extensively in IFTTT for iPhone, most famously in the app intro.

Answer 2

Recently, I created a UIScrollView subclass called DRDynamicSlideShow to easily implement touch-interactive slide shows like IFTTT's. Check it out, it takes only 1 line of code per animation!
