Sam Davies of ShinobiControls wrote up a nice tutorial of UIKit
Dynamics, walking through how to recreate the iconic Newton’s
Cradle with very little code. Between this and Sprite Kit’s physics engine,
I’m quite impressed with these new APIs. But please, don’t overdo it when using
this in your application. The last thing we need is an uproar declaring
physics engines as the new skeuomorphism, right? Right?!?!
By the way, this is the first part of Sam’s daily series, iOS 7
Day-by-Day, and it looks like it’ll be a great resource to catch up on
all the changes.
