UIGestureRecognizer giving me error on ipod but not in iphone simulator?

Question

In my program, I have declared a UIPanGestureRecognizer and it works very well in the iPhone simulator. However, when I run it on my iPod (iOS 3.1) it gives me the error [UIPanGestureRecognizer locationInView:]: unrecognized selector sent to instance 0x11cd80. Does anybody know how to fix this? Thanks!

Answer 1

UIPanGestureRecognizer is available in iOS 3.2 and later. Please check the Apple documentation
