The Gestures library primarily 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
