objective c - Paging Horizontally with vertical scroll on each page! -

-

in app use page control , uiscrollview page horizontally, i'd able enable vertical scrolling on each page. know can nest uiscrollviews in order achieve this, there 1 problem in project. each of pages uses view controller consisting of view, background image (different image each page). background image should not move while scrolling , down.

now want ability have buttons, regular rect buttons, create in interface builder (since want able design , update positions easily) , can scrolled vertically.

so should this:

you see screen page-control on bottom, above image buttons on it. when scroll sideways, go page, again image (another one) , different buttons. whenever scroll vertically on page, buttons should scrollable (so can have lot of buttons on 1 page), image should maintain it's position.

so figured, add scroll view on top of view background image. works fine since have buttons hovering on background image , have separate nib file each page including buttons. when this, scrollview buttons becomes un-scrollable vertically. don't know why happening, suggest me how achieve wanted result?

i'd really grateful!

thanks,

fabian
