Answer 1

why not just the below as a variation on obuseme's response

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{

         UITouch *aTouch = [touches anyObject];
         CGPoint newLocation = [aTouch locationInView:self.view];
         CGPoint prevLocation = [aTouch previousLocationInView:self.view];

         if (newLocation.x > prevLocation.x) {
                 //finger touch went right
         } else {
                 //finger touch went left
         }
         if (newLocation.y > prevLocation.y) {
                 //finger touch went upwards
         } else {
                 //finger touch went downwards
         }
}
