How do I change the scrolling distance of a UIView to be like Safari app

I want to have a UIScrollView that scrolls less then the full screen so that it looks like the Safari app does when you go to mak开发者_运维技巧e a new tab or look at all the tabs. What property would this be?

When viewing "tabs" in Mobile Safari each tab is a UIWebView placed in a paged UIScrollView. When you "zoom out" to switch between them a CGAffineTransform to reduce the scale of the web view is being applied.
