UITouch

---

A UITouch holds information about where a touch occurred.

Example:

You can handle touches in any UIView (UIImageView, ...) by writing a subclass of UIView (UIImageView, ...) and adding one or more of the following methods:
// don't forget to call
// [yourUIViewObject setUserInteractionEnabled:YES];
// declare CGPoint touchedStartPos;
// as an instance variable
// DO NOT put these methods in your
// UIViewController class

// this method is called when the
// UIView is touched
-(void) touchesBegan:(NSSet*) touches
   withEvent:(UIEvent*) event
{
   touchedStartPos = [[touches anyObject]
    locationInView:self];
   // do whatever you want to do
}

// this method is called when
// the UIView is dragged
-(void) touchesMoved:(NSSet*) touches
   withEvent:(UIEvent*) event
{
   CGPoint touchedEndPos =
    [[touches anyObject] locationInView:self];
   // do whatever you want to do
}

// this method is called when the
// touch of the UIView has ended
-(void) touchesEnded:(NSSet*) touches
   withEvent:(UIEvent*) event
{
   CGPoint touchedEndPos =
    [[touches anyObject] locationInView:self];
   // do whatever you want to do
}
