TouchPhase Enumeration  

Describes phase of a finger touch.

Values

Began	A finger touched the screen.
Moved	A finger moved on the screen.
Stationary	A finger is touching the screen but hasn't moved.
Ended	A finger was lifted from the screen. This is the final phase of a touch.
Canceled	The system cancelled tracking for the touch, as when (for example) the user puts the device to her face or more than five touches happened simultaneously. This is the final phase of a touch.
