Summary

In this hour, we’ve given the gesture recognizer architecture a good workout. Using the gesture recognizers provided through iOS, you can easily recognize and respond to taps, swipes, pinches, rotations, and more—without any complex math or programming logic.

You also learned how to make your applications respond to shaking: Just make them first responders and implement the motionEnded:withEvent method. Your ability to present your users with interactive interfaces just increased dramatically.
