use two gesture recognizers, and assign one to left swipes and one to rigt swipes. then you can react accordingly to the gestures. or do you need a panning gesture? thats slightly more complicate, as you need the direction of the movement, i.e. a negative value is left, and a positive value is right. ask if you have problems with this, heres a link to a great tutorial: http://www.raywenderlich.com/6567/uigesturerecognizer-tutorial-in-ios-5-pinches-pans-and-more and heres the class ref for pangesturerecongnizers. you want the -translationInView: method. it will return the point your view was dragged to. now determine if it was left or right, and react.
