Gesture Recognizers with Delegates for Controlling and Modifying Gesture Recognition

A computer readable storage medium storing one or more programs for execution by an electronic device with a touch-sensitive surface, the one or more programs including a software application that includes a plurality of views and an application state of the software application, the software application including instructions for:

• displaying one or more views of the plurality of views, wherein a respective view of the one or more displayed views includes one or more respective gesture recognizers, a respective gesture recognizer having a corresponding delegate;
• detecting one or more touches, on the touch-sensitive surface, each having a touch position that falls within one or more of the displayed views;
• processing a respective touch of the one or more touches, including:
• obtaining a receive touch value based on the application state by executing, after detecting the one or more touches, the delegate corresponding to the respective gesture recognizer;
• 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 of the respective touch by the respective gesture recognizer and in accordance with the receive touch value determined by the delegate corresponding to the respective gesture recognizer;
• and
• executing the software application in accordance with the outcome of the processing of the respective touch by the respective gesture recognizer.

An electronic device, comprising:

• a touch-sensitive surface;
• one or more processors;
• memory;
• one or more programs stored in the memory and configured to be executed by the one or more processors, the one or more programs including a software application that includes a plurality of views and an application state of the software application, the software application including instructions for:
• displaying one or more views of the plurality of views, wherein a respective view of the one or more displayed views includes one or more respective gesture recognizers, a respective gesture recognizer having a corresponding delegate;
• detecting one or more touches, on the touch-sensitive surface, each having a touch position that falls within one or more of the displayed views;
• processing a respective touch of the one or more touches, including:
• obtaining a receive touch value based on the application state by executing, after detecting the one or more touches, the delegate corresponding to the respective gesture recognizer;
