Questions tagged [uitouch]

UITouch is a class from UIKit framework in Apple iOS. A UITouch object represents the presence or movement of a finger on the screen for a particular event.

A UITouch object includes methods for accessing the view or window in which the touch occurred and for obtaining the location of the touch in a specific view or window. it also lets you find out when the touch occurred, whether the user tapped more than once, whether the finger is swiped (and if so, in which direction), and the phase of a touch—that is, whether it began, moved, or ended the gesture, or whether it was canceled.

A UITouch object is persistent throughout a multi-touch sequence. You should never retain an UITouch object when handling an event. If you need to keep information about a touch from one phase to another, you should copy that information from the UITouch object.
