Get swipe direction in Cocoa
In my program I have created a UISwipeGestureRecognizer in a header file and configured its directions to be UISwipeGestureRecognizerDirectionLeft and UISwipeGestureRecognizerDirectionRight in the implementation file. I have set it to call a method called handleSwipe when the gesture is recognized. It successfully calls this method, but when I try to determine the direction of that gesture recognizer using its direction property it does not give me a value. Why so?
You cannot use one gesture recognizer to recognize two different gestures. Create two gesture recognizers, one in either direction and point them to handleSwipLeft and handleSwipeRight (that then calls handleSwipe:withDirection: or something).
