Gesture Recognizers with Delegates for Controlling and Modifying Gesture Recognition

A software application includes a plurality of views and an application state. The application includes instructions for displaying one or more views, where a respective view includes a respective gesture recognizer having a corresponding delegate, detecting one or more touches on a touch-sensitive surface, and processing a respective touch. The processing includes obtaining a receive touch value based on the application state by executing the delegate; when the receive touch value meets predefined criteria, processing the respective touch at the respective gesture recognizer; and conditionally sending information corresponding to the respective touch to the software application in accordance with an outcome of the processing by the respective gesture recognizer and in accordance with the receive touch value determined by the delegate. The software application is executed in accordance with the outcome of the processing of the respective touch by the respective gesture recognizer.
