Event recognition

An electronic device, comprising:

• a touch-sensitive surface;
• 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:
• detecting a sequence of sub-events as part of a touch event associated with a view;
• determining that the sequence of sub-events does not correspond to one of one or more predefined sequences of sub-events for the view associated with the touch event;
• and
• in accordance with a determination that the sequence of sub-events does not correspond to one of the one or more predefined sequences of sub-events, sending a touch cancel event to the view associated with the touch event.

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

• detecting a sequence of sub-events as part of a touch event associated with a view;
• determining that the sequence of sub-events does not correspond to one of one or more predefined sequences of sub-events for the view associated with the touch event;
• and
• in accordance with a determination that the sequence of sub-events does not correspond to one of the one or more predefined sequences of sub-events, sending a touch cancel event to the view associated with the touch event.

A method performed at an electronic device with a touch-sensitive surface, the method comprising:

• detecting a sequence of sub-events as part of a touch event associated with a view;
• determining that the sequence of sub-events does not correspond to one of one or more predefined sequences of sub-events for the view associated with the touch event;
• and
• in accordance with a determination that the sequence of sub-events does not correspond to one of the one or more predefined sequences of sub-events, canceling the touch event.
