the verticall scroll works just in the opposite direction. If you try to put a list of elements inside a vertical scroll, it behaves like the elements are stacked to the top of the screen, instead of the botton, so you have to scroll in the opposite direction. We could say its scrolling upside down, as people complains in other posts:
I just want to help, if you need it I can prepare a simple example and send it to you.
ps: for now, to make it work I rotated 180 degrees the ccscrollview and its content. Not nice but works.
