    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 5 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 10 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.
