Devices and methods for processing inputs using gesture recognizers

Abstract:

An electronic device displays, on a display, a user interface of an application. The user interface includes a plurality of views arranged in a view hierarchy that defines a first relationship between a first view and a second view. The first view includes a first gesture recognizer, and the second view includes a second gesture recognizer. The device detects, via the input device, an input at a first location that corresponds to the displayed user interface, and processes the input using a gesture recognition hierarchy that includes the first gesture recognizer and the second gesture recognizer. A second relationship between the first gesture recognizer and the second gesture recognizer is determined based on the first relationship between the first view and the second view in the view hierarchy.
