How to use a UIScrollview with a few images

I have not used a UIScrollView before, and I just wanted to know how I could use paging in a UIScrollView, where there would be a different image on each page, and depending on the page currently selected I would set the image on that page to a separate UIImageView's image.

So if anyone c开发者_如何学JAVAould tell me how to do this that would be great.

The Snipplr reference here gives you a great barebones look into how to set this up.
