Moving images sliding in a "rail"

Question

I have an image which I would like to move around in a rail.

When I put my finger on it, i will only be able to move it up and down, and not from side to side. And how do I make them "stick" at either the top or the bottom? (or both)

Thanks.

By not changing the the x-coord when drawing the image in the new location? — trojanfoe, Jan 06 '14 at 13:39

Check out the answer(s) here - UIPanGestureRecognizer - Only vertical or horizontal

Just do this for the vertical pan gesture recognizer, it works for me:

 - (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)panGestureRecognizer {
     CGPoint translation = [panGestureRecognizer translationInView:someView];
     return fabs(translation.y) > fabs(translation.x); }

@trojanfoe Yes, but how would you get that sweet sweet rep if you just close voted it? – JustSid Jan 06 '14 at 13:42
