iPhone Quartz Demo, rerender PDF

How should I modify the QuartzDemo that comes with the iPhone so that it re-renders the PDF view like UIWebView does when you zoom in?




Got an answer from Apple, sharing it here for completeness:

Apple doesn't have any sample code that demonstrates how to do this at the moment, but Bill Dudney (who is now an evangelist at Apple) has a great blog post about using the CATiledLayer on the iPhone to draw PDFs. I would suggest taking a look at his two posts on the CATiledLayer class http://bill.dudney.net/roller/objc/entry/tiledlayer_on_the_iphone and http://bill.dudney.net/roller/objc/entry/catiledlayer_example.
