One of the greatest things about the iOS platform and applications people see on it is its beauty. Smooth gradients, consistent transitions, and animations that illustrate the transition of UI elements from one state to another. Animations are more than flashy eye-candy; they tell the user what’s happening. If an element is being deleted, instead of it simply disappearing it fades or slides out of view. Unlike traditional desktop or web applications where a “2 items deleted” statusbar message is necessary, these animations are in many cases enough.
Knowing where to start with animations can be a problem for developers though, because there’s many different steps involved. Instead of walking you through it fully here in the blog, I highly recommend you watch the WWDC 2010 videos on the topic. I truly mean it; anything I do here will simply be a rehash of that material, and I don’t see the point in reproducing perfectly good documentation unnecessarily.
