It provides a predictable wrapper of the responder handlers provided by the
gesture responder system.
For each handler, it provides a new gestureState object alongside the
-normal event.
A gestureState object has the following:
stateID - ID of the gestureState- persisted as long as there at least
+native event object:A native event is a synthetic touch event with the following form:
nativeEventchangedTouches - Array of all touch events that have changed since the last eventidentifier - The ID of the touchlocationX - The X position of the touch, relative to the elementlocationY - The Y position of the touch, relative to the elementpageX - The X position of the touch, relative to the root elementpageY - The Y position of the touch, relative to the root elementtarget - The node id of the element receiving the touch eventtimestamp - A time identifier for the touch, useful for velocity calculationtouches - Array of all current touches on the screenA gestureState object has the following:
stateID - ID of the gestureState- persisted as long as there at least
one touch on screenmoveX - the latest screen coordinates of the recently-moved touchmoveY - the latest screen coordinates of the recently-moved touchx0 - the screen coordinates of the responder granty0 - the screen coordinates of the responder grantdx - accumulated distance of the gesture since the touch starteddy - accumulated distance of the gesture since the touch startedvx - current velocity of the gesturevy - current velocity of the gesturenumberActiveTouches - Number of touches currently on screeen
