I have a UIScrollView with 10 pages. I am able to flick between them. I also want to have 2 buttons (a back button and a next button) which when touched will go to the previous or next page. I can't seem to figure out a way to do this though. A lot of my code comes from Apple's page control sample code. Can anybody help?

Thanks

You just tell the buttons to scroll to the page's location:

CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * pageNumberYouWantToGoTo;
frame.origin.y = 0;
[scrollView scrollRectToVisible:frame animated:YES];
