02 Oct 2010 Simple UIScrollView / CATiledLayer PDF Example

Here is an example of using a CATiledLayer to present a large, zoomable PDF in a UIScrollView.

It’s about 50 lines of code in addition to what’s provided by the view-based app template.

If you’re wondering why UIScrollView zooming is designed the way it is, CATiledLayer might be the explanation you’re looking for.

Hope it proves useful to somebody!
