This a iOS 7 demo of user interaction with UIView achieved via UIDynamics.

The view rotates and moves as user pans over it. When the gesture ends, if the velocity is smaller than a threshold, the view snaps back to its original positon, otherwise it gains an acceleration in the direciton of its veleocity and moves out of the screen.

Design is inspired by TweetBot.

Implementation heavily relied on this answer on StackOverflow.
