The Gestures library provides gesture recognizers to detect gestures
through mtouch events that occur when you place one or more fingers on a touch
screen.
Here is a summary of what the Gestures library provides:
- Gesture Recognizers:
- Self-contained state machines that detect gestures through
mtouch events.
- Gesture Sets:
- Collections of gesture recognizers that interface between
the gesture recognizers and the application.
- Gesture buckets:
- Lists of gesture recognizers that have not yet been processed.
- Gesture timers:
- Data type definitions and functions for manipulating timers
used for determining the time elapsed between touches or the
length of a touch.
- Event lists:
- Data type definitions and functions for lists of mtouch events
to be processed by the gesture sets
- Data types and Helper functions:
- Data type definitions and helper functions for
recognizing gestures from the touch screen.
