Recently I started working on a new project for which there will be an iPhone app. So far I have found 2 hidden nuggets I would like to share with any other iPhone developers out there that may be reading this.
This simple set of classes very easily allows you to map your XML coming in off of a URL (Like a REST based service) to an object.
This is basically a simplistic ORM (object relational mapper) written in objective c and meant for the iPhone.
As I discover more tidbits I will try to make note of them here. Also I will try to blog in a bit more detail about them and my project in near future.
