At an electronic device, a user input is detected that corresponds to a respective user interface element in a portion of a user interface that is associated with a first standard gesture recognizer and a first supplemental gesture recognizer. The user input is processed in accordance with the first standard gesture recognizer and the first supplemental gesture recognizer. In accordance with a determination that content associated with the respective user interface element cannot be added to a drag operation, the device fails to recognize the user input using the first supplemental gesture recognizer, and processes the user input using the first standard gesture recognizer. On the other hand, in accordance with a determination that the content associated with the respective user interface element can be added to the drag operation, a gesture is recognized using the first supplemental gesture recognizer and the content is added to the drag operation.

Devices, methods, and graphical user interfaces for touch input processing

An electronic device, while displaying a user interface of an application, detects a user input on a portion of the user interface associated with a plurality of gesture recognizers. A first set of standard gesture recognizers are associated with the portion of the user interface by the application; a second set of supplemental gesture recognizers are associated with the portion of the user interface by a system process; and a first failure requirement determines which gesture recognizers must fail before other gesture recognizers can recognize a user input. In one example, the first failure requirement is that a particular standard gesture recognizer (e.g., an intensity-based gesture recognizer) must fail before a particular supplemental gesture recognizer (e.g., a drag start gesture recognizer) can recognize a user input.

An electronic device, while displaying a user interface for a first application, receives at the first application information that describes a first touch detected at a location on the touch-sensitive surface that corresponds to a respective user interface object. In accordance with a determination that the first touch meets predefined criteria associated with initiating a respective type of interface operation, the device initiates a user interface operation of the respective type involving the respective user interface object. The first application receives instructions to ignore the first touch with respect to user interface operations other than the respective type of interface operation, and ignores the first touch with respect to user interface operations other than the respective type of interface operation. In some embodiments, the respective type of interface operation is a drag operation, for dragging an object in or from a view of the first application.
