UIPanGestureRecognizer starting point is off

Question

I have a UIView that has a UIPanGestureRecognizer attached to it the gesture is working fine except that the starting point is not where the pan first started it is usually

Answer 1

To get around this you could try reseting the translation point when the gesture recognizer begins. For example, start your action method out like so:

- (void)panGesture:(UIPanGestureRecognizer *)recognizer;
{
    if ( recognizer.state == UIGestureRecognizerStateBegan )
    {
        CGPoint point = ...; // The view's initial origin.
        UIView *superview = [recognizer.view superview];
        [recognizer setTranslation:point inView:superview];
    }
}
