I find that I am starting new iPhone projects under xCode all the time. And there are certain things that I am creating over, and over, and over again. One of the common things I find myself doing, is REMOVING all references to Interface Builder*. So I created NXTemplates. A templating library that does not utilize Interface Builder and will hopefully grow.
Path to install the templates
Go easy on me. I may be doing something wrong so I am starting a thread over on iphonedevsdk.
*(Interface Builder is not cool, and I would suggest that if you plan on working with the iPhone SDK, you stop using it as soon as possible. The reasons behind this are beyond the scope of this post.)
