Abstract:
An electronic device displays a user interface of a first third-party application that runs within an operating system. The device detects an input on a touch-sensitive surface at a location that corresponds to a first portion of the user interface of the first third-party application. If the input meets first gesture recognition criteria and the input meets first intensity criteria specified by the first third-party application, the device performs the first operation associated with the first portion of the user interface of the first third-party application. If the input meets the first gesture recognition criteria but does not meet the first intensity criteria specified by the first third-party application, the device forgoes performance of the first operation associated with the first portion of the user interface of the first third-party application.
