Abstract

A method includes displaying one or more views of a view hierarchy, and executing software elements associated with a particular view. Each particular view includes event recognizers. Each event recognizer has one or more event definitions, and an event handler that specifies an action for a target and is configured to send the action to the target in response to event recognition. The method includes detecting a sequence of sub-events, and identifying one of the views of the view hierarchy as a hit view that establishes which views are actively involved views. The method includes delivering a respective sub-event to event recognizers for each actively involved view. A respective event recognizer has event definitions, and one of the event definitions is selected based on the internal state. The respective event recognizer processes the respective sub-event prior to processing a next sub-event in the sequence of sub-events.

Claims

1. A method, comprising:

at an electronic device with a touch-sensitive display, the electronic device configured to execute at least a first software application and a second software application, the first software application including a first set of one or more gesture recognizers, the second software application including one or more views and a second set of one or more gesture recognizers, and respective gesture recognizers having corresponding gesture handlers;

displaying at least a subset of the one or more views of the second software application; and

while displaying at least the subset of the one or more views of the second software application;

detecting a sequence of touch inputs on the touch-sensitive display, the sequence of touch inputs including a first portion of one or more touch inputs and a second portion of one or more touch inputs subsequent to the first portion; and

during a first phase of detecting the sequence of touch inputs;

delivering the first portion of one or more touch inputs to the first software application and the second software application;

identifying from gesture recognizers in the first set, one or more matching gesture recognizers that recognize the first portion of one or more touch inputs; and

processing the first portion of one or more touch inputs with one or more gesture handlers corresponding to the one or more matching gesture recognizers.

2. The method of claim 1, wherein the detecting occurs while touch inputs in the first portion of one or more touch inputs at least partially overlap at least one of the displayed views of the second software application.

3. The method of claim 1, wherein the displaying includes displaying at least a subset of the one or more views of the second software application without displaying any view of the first software application.

4. The method of claim 1, wherein the displaying includes displaying at least a subset of the one or more views of the second software application without displaying a view of any other application.

5. The method of claim 1, including:

during a second phase of detecting the sequence of touch inputs, subsequent to the first phase;

delivering the second portion of one or more touch inputs to the first software application without delivering the second portion of one or more touch inputs to the second software application;

identifying from the one or more matching gesture recognizers a second matching gesture recognizer that recognizes the sequence of touch inputs; and

processing the sequence of touch inputs with a gesture handler corresponding to the respective matching gesture recognizer.

6. The method of claim 5, wherein processing the sequence of touch inputs with the gesture handler corresponding to the respective matching gesture recognizer includes displaying one or more views of the first software application.

7. The method of claim 5, wherein processing the sequence of touch inputs with the gesture handler corresponding to the respective matching gesture recognizer includes replacing the display of the one or more views of the second software application with display of one or more views of the first software application.

8. The method of claim 5, wherein the electronic device concurrently executes the first software application, the second software application, and a third software application;

and processing the sequence of touch inputs with the gesture handler corresponding to the respective matching gesture recognizer includes replacing the one or more displayed views of the second software application with one or more views of the third software application.

9. The method of claim 5, wherein processing the sequence of touch inputs with the gesture handler corresponding to the respective matching gesture recognizer includes:

displaying in a first predefined area of the touch-sensitive display a group of open application icons that correspond to at least some of a plurality of concurrently open applications; and

concurrently displaying at least a subset of the one or more views of the second software application.

10. The method of claim 1, wherein the first software application is an application launcher.

11. The method of claim 1, wherein the first software application is an operating system application.

12. An electronic device, comprising:

a touch-sensitive display;

one or more processors; and

memory storing one or more programs for execution by the one or more processors, the one or more programs including;

at least a first software application and a second software application, the first software application including a first set of one or more gesture recognizers, the second software application including one or more views and a second set of one or more gesture recognizers, and respective gesture recognizers having corresponding gesture handlers,

wherein the one or more programs include instructions for;

displaying at least a subset of the one or more views of the second software application; and

while displaying at least the subset of the one or more views of the second software application;

detecting a sequence of touch inputs on the touch-sensitive display, the sequence of touch inputs including a first portion of one or more touch inputs and a second portion of one or more touch inputs subsequent to the first portion; and

during a first phase of detecting the sequence of touch inputs;

delivering the first portion of one or more touch inputs to the first software application and the second software application;

identifying from gesture recognizers in the first set, one or more matching gesture recognizers that recognize the first portion of one or more touch inputs; and

processing the first portion of one or more touch inputs with one or more gesture handlers corresponding to the one or more matching gesture recognizers.

13. The electronic device of claim 12, wherein the instructions for detecting include instructions for detecting the sequence of touch inputs while touch inputs in the first portion of one or more touch inputs at least partially overlap at least one of the displayed views of the second software application.

14. The electronic device of claim 12, wherein the instructions for displaying include instructions for displaying at least a subset of the one or more views of the second software application without displaying any view of the first software application.

15. The electronic device of claim 12, wherein the one or more programs include instructions for:
