Control selection approximation

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 instructions for:

• displaying on the touch-sensitive display a user interface of an application, the displayed user interface including a plurality of regions that are arranged in multiple hierarchical levels, the plurality of regions including a respective region at a respective hierarchy level, the respective region having two or more child regions at a hierarchy level below the respective hierarchy level;
• detecting on the touch-sensitive display a first contact at a first location that corresponds to the respective region and that does not correspond to any of the two or more child regions of the respective region;
• in response to detecting the first contact, determining whether the application is configured to process the first contact in conjunction with the respective region;
• in accordance with a determination that the application is not configured to process the first contact in conjunction with the respective region:
• determining whether the application is configured to process the first contact in conjunction with at least one child region of the two or more child regions of the respective region;
• in accordance with a determination that the application is configured to process the first contact in conjunction with at least one child region of the two or more child regions of the respective region:
• identifying a respective child region, of the two or more child regions of the respective region, in accordance with positions of the child regions relative to the first location;
• and
• processing the first contact in conjunction with the identified respective child region using the application.

A non-transitory computer readable storage medium storing one or more programs for execution by one or more processors in an electronic device with a touch-sensitive display, the one or more programs including instructions for:

• displaying on the touch-sensitive display a user interface of an application, the displayed user interface including a plurality of regions that are arranged in multiple hierarchical levels, the plurality of regions including a respective region at a respective hierarchy level, the respective region having two or more child regions at a hierarchy level below the respective hierarchy level;
• detecting on the touch-sensitive display a first contact at a first location that corresponds to the respective region and that does not correspond to any of the two or more child regions of the respective region;
• in response to detecting the first contact, determining whether the application is configured to process the first contact in conjunction with the respective region;
• in accordance with a determination that the application is not configured to process the first contact in conjunction with the respective region:
• determining whether the application is configured to process the first contact in conjunction with at least one child region of the two or more child regions of the respective region;
• in accordance with a determination that the application is configured to process the first contact in conjunction with at least one child region of the two or more child regions of the respective region:
• identifying a respective child region, of the two or more child regions of the respective region, in accordance with positions of the child regions relative to the first location;
• and
• processing the first contact in conjunction with the identified respective child region using the application.
