I question whether it makes sense to implement custom UI with transparent PNGs like the slideshow describes. It's pretty tough to get it exactly right, and that approach leads to a lot of interfaces that look a bit off. On iOS, with some drawing code you can build custom table cells that are more flexible, are easy to reuse and look exactly right. (Kudos to the author by the way -- the design methodology in this presentation looks really good).
