Replicating iPhone Safari's Tabs

Question

I am wondering if there is some way to replicate Safari (on the iPhone's) tab behavior of scrolling through the webpages. Is it an API or some code that makes this happen, and how would I create this in my own app? I saw this post: UIScrollView horizontal paging like Mobile Safari tabs however I have not been able to follow the steps that the answer provided.

Thanks for any help!

EDIT: I have found the Apple Example called PageControl and have slightly modified it to display a small jpg instead of the colors. However, this lags a lot on scroll - So now my question is more if there is any way to make it not lag. Maybe some IB Preference that I missed transferring or a different file format?

A little more detail regarding the lagging implementation would be helpful. How big are you images? — mrueg, Sep 04 '09 at 09:10
They are about 100px by 100px... Not that big. And I am not using any transparency in them. — individualtermite, Sep 04 '09 at 23:59

I think it is the other way around... ;) But I agree you should PNG where ever you can. – Pieter Jongsma Sep 06 '09 at 20:45

Are you loading the images off screen?

The key is to only update the views +1 and -1 and to remove any views that are further away. Matt Gallagher did a nice write up of this:

That should make your Scroll view screaming fast.
