Proper way to get the direction of pan gesture recognizer

[devangmundhra]

Hi,

In the HorizontalInteractionController, the direction of the UIPanGestureRecognizer is found by:

CGPoint translation = [gestureRecognizer translationInView:gestureRecognizer.view.superview];
BOOL rightToLeftSwipe = translation.x < 0;

However, I think with this way, a pan gesture will always start with a translation of 0. The correct way to get the direction would be-

CGPoint vel = [gestureRecognizer velocityInView:gestureRecognizer.view];
BOOL rightToLeftSwipe = vel.x < 0;

Thanks a lot for this - I'll test this out and update accordingly.
