Gesture Recognizers are Apple's answer to the problem: How do I keep all those touches straight!?!? It's about tracking touch state over time, and UIGestureRecognizer subclasses give us a standard and composable way to manage that complexity. We'll look at how recognizers work, how they compete to decide which one "wins", see a custom complex gesture recognizer in action, and discuss how to leverage this in your applications. Complete with demo and sample code!
