UIScrollViews and Dynamically Creating Pages

I want to be able to dynamically populate UIScrollView. Like how it is done for row views in UITableView. I have a class that takes in some parameters and creates the respective view when it scrolls. Currently I have 8 views.

These 8 views have different background image, image and label according to the page number it is currently in. However the basic skeleton for this view is the same. What i am doing right now is in ViewDidLoad I am creating 8 views and add them as subviews and scroll over.

I don't want to do this. I want to create three views and the rest i want to populate when the user scrolls a page and then a page etc. How do i do this? ANy pointers/tutorial?

Check the two most recent WWDC videos for two excellent sessions regarding expert use of UIScrollViews. Additionally you can review a brief tutorial here, written by the well known cocoa expert, Matt Gallagher.

First of all you calculate the ContentSize for the scrollview (when you want to use the iPad in landscapemode with 8 pages then the width should be 1024*8 = 8192px and the height 768px).

Then you should implement the UIScrollView Delegate method:

scrollViewDidEndDecelerating:

In this Method you check on which page you currently are with the contentOffset property of the scrollview and start updating your left and right hidden views..

Hope this helps you a bit.
