Abstract

A method executes software including a view hierarchy with a plurality of views which displays one or more views of the view hierarchy. The method executes software elements associated with a particular view, wherein each particular view includes event recognizers. Each event recognizer has an event definition based on sub-events, and an event handler that specifies an action for a target, and is configured to send the action to the target in response to an event recognition. The method detects a sequence of sub-events, and identifies one of the views of the view hierarchy as a hit view that establishes which views in the hierarchy are actively involved views. The method delivers a respective sub-event to event recognizers for each actively involved view, wherein each event recognizer for actively involved views in the view hierarchy processes the respective sub-event prior to processing a next sub-event in the sequence of sub-events.

First claim

What is claimed is:

1 . A non-transitory computer readable storage medium storing software that includes a view hierarchy with a plurality of views and instructions for execution by one of more processors of an electronic device having a touch-sensitive display, the instructions for:
at the electronic having the touch-sensitive display:
detecting one or more touches on the touch-sensitive display within a view that corresponds to a region of a user interface displayed on the touch-sensitive display;
obtaining a sequence of touch sub-events that correspond to one or more touches within the view;
providing the sequence of touch sub-events to a plurality of gesture recognizers that are associated with the view, including a first gesture recognizer and a second gesture recognizer; and
detecting a transition in state of the first gesture recognizer with respect to recognizing a gesture based on the sequence of touch sub-events; and,
in response to detecting the transition in state of the first gesture recognizer:
in accordance with a determination that the first gesture recognizer has transitioned to a state in which a gesture that corresponds to the sequence of touch sub-events has been recognized, transitioning the second gesture recognizer into a state in which the second gesture recognizer is prevented from recognizing a gesture that corresponds to the sequence of touch sub-events.

2 . The non-transitory computer readable storage medium of claim 1 , wherein the software includes instructions for, responding detecting the transition in state of the first gesture recognizer by enabling the second gesture recognizer, in accordance with a determination that the first gesture recognizer has transitioned to a state in which the first gesture recognizer is prevented from recognizing a gesture that corresponds to the first sequence of inputs, to recognize a gesture that corresponds to the sequence of touch sub-events.

3 . The non-transitory computer readable storage medium of claim 1 , wherein the software includes instructions for:
detecting that the sequence of touch sub-events corresponds to a gesture recognized by the first gesture recognizer; and, in response to detecting that the sequence of touch sub-events corresponds to a gesture recognized by the first gesture recognizer, preventing the second gesture recognizer from recognizing a gesture that corresponds to the sequence of touch sub-events.

4 . The non-transitory computer readable storage medium of claim 3 , wherein preventing the second gesture recognizer from recognizing a gesture that corresponds to the sequence of touch sub-events includes transitioning the second gesture recognizer into a state in which the second gesture is prevented from recognizing a gesture that corresponds to the sequence of touch sub-events.

5 . The non-transitory computer readable storage medium of claim 1 , wherein
the touch sub-events are provided to the plurality of gesture recognizers over a period of time, and during the period of time:
the first gesture recognizer evaluates the sequence of touch events to determine whether the sequence of touch events meet gesture recognition criteria for the first gesture recognizer; and
the second gesture recognizer evaluates the sequence of touch events to determine whether the sequence of touch events meet gesture recognition criteria for the second gesture recognizer.

6 . The non-transitory computer readable storage medium of claim 5 , wherein the evaluation of the sequence of touch events by the first gesture recognizer occurs concurrently with the evaluation of the sequence of touch events by the second gesture recognizer.

7 . The non-transitory computer readable storage medium of claim 1 , wherein the first gesture recognizer is configured to delay delivering the sequence of touch sub-events to the view until after the first gesture recognizer fails to recognize the sequence of touch sub-events.

8 . The non-transitory computer readable storage medium of claim 1 , wherein the software includes instructions for, in accordance with a determination that the second gesture recognizer has transitioned to the state in which the gesture that corresponds to the sequence of touch sub-events has been recognized, causing the first gesture recognizer to transition into a state in which the first gesture recognizer is prevented from recognizing the gesture that corresponds to the sequence of touch sub-events.

9 . The non-transitory computer readable storage medium of claim 1 , wherein the second gesture recognizer is associated with a list of one or more gesture recognizers and the list of one or more gesture recognizers includes the first gesture recognizer.

10 . An electronic device, comprising:
a display; one or more processors; and memory storing software that includes a view hierarchy with a plurality of views and instructions, which, when executed by the one or more processors, cause the electronic device to perform a method including:
detecting one or more touches on the touch-sensitive display within a view that corresponds to a region of a user interface displayed on the touch-sensitive display;
obtaining a sequence of touch sub-events that correspond to one or more touches within the view;
providing the sequence of touch sub-events to a plurality of gesture recognizers that are associated with the view, including a first gesture recognizer and a second gesture recognizer; and
detecting a transition in state of the first gesture recognizer with respect to recognizing a gesture based on the sequence of touch sub-events; and,
in response to detecting the transition in state of the first gesture recognizer:
in accordance with a determination that the first gesture recognizer has transitioned to a state in which a gesture that corresponds to the sequence of touch sub-events has been recognized, transitioning the second gesture recognizer into a state in which the second gesture recognizer is prevented from recognizing a gesture that corresponds to the sequence of touch sub-events.

11 . The electronic device of claim 10 , wherein the software includes instructions for, responding detecting the transition in state of the first gesture recognizer by enabling the second gesture recognizer, in accordance with a determination that the first gesture recognizer has transitioned to a state in which the first gesture recognizer is prevented from recognizing a gesture that corresponds to the first sequence of inputs, to recognize a gesture that corresponds to the sequence of touch sub-events.

12 . A method, comprising,
at a device with a touch-sensitive display:
detecting one or more touches on the touch-sensitive display within a view that corresponds to a region of a user interface displayed on the touch-sensitive display;
obtaining a sequence of touch sub-events that correspond to one or more touches within the view;
providing the sequence of touch sub-events to a plurality of gesture recognizers that are associated with the view, including a first gesture recognizer and a second gesture recognizer; and
detecting a transition in state of the first gesture recognizer with respect to recognizing a gesture based on the sequence of touch sub-events; and,
in response to detecting the transition in state of the first gesture recognizer:
in accordance with a determination that the first gesture recognizer has transitioned to a state in which a gesture that corresponds to the sequence of touch sub-events has been recognized, transitioning the second gesture recognizer into a state in which the second gesture recognizer is prevented from recognizing a gesture that corresp
