Get swipe direction in Cocoa Touch

You're not using the UISwipeGestureRecognizercorrectly. Its direction is always going to be what you've set it to (in this case UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionLeft, or 3).

If you want to capture swipes left and right that you can differentiate between, you'll have to set up a separate recognizer for each. Apple does this in their SimpleGestureRecognizers sample.

What you have to do is just change the codes for adding gesture recognizer.

UISwipeGestureRecognizer *leftRecognizer;leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];[leftRecognizer setDirection: UISwipeGestureRecognizerDirectionLeft];[[self view] addGestureRecognizer:leftRecognizer];[leftRecognizer release];UISwipeGestureRecognizer *rightRecognizer;rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];[rightRecognizer setDirection: UISwipeGestureRecognizerDirectionRight];[[self view] addGestureRecognizer:rightRecognizer];[rightRecognizer release];  

UISwipe... is iOS. But for Cocoa, you can use -swipeWithEvent: in your view class. See the documentation at:http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/EventOverview/HandlingTouchEvents/HandlingTouchEvents.html#//apple_ref/doc/uid/10000060i-CH13-SW10
