Semantic Zoom in iOS

How would one go about creating a semantic zoom type interface in iOS4? By semantic zoom I mean that as the user zooms in on an object it reveals more and more details, and vice versa when zooming out.

Any tips appreciated, thanks!

The "PhotoScroller" sample code provided by Apple has a tiled zoom technique that works very well. I have reused it across multiple apps. It relies on CATiledLayer. Download the sample code and you should have what you need.

I think there was a WWDC session video on this and it used a UIScrollView and tiling. When the user zoomed a more detailed image was shown on the tiles. Take a look at the session videos (link is in the developer center and you will need a developer account).
