My first post has to be App Coda. When I started teaching myself Objective-C and learning how to make iOS apps, I learned the most from App Coda and Ray Wenderlich. App Coda is a 100% free site that the author walks you through step by step (in amazing detail for newbies) how to accomplish programming tasks in Xcode and MORE IMPORTANTLY why you are doing them.
The site has tutorials that cover a variety of topics. While they don’t cover everything the material they do have is solid gold. For anyone trying to get into iOS programming without much of a background I would recommend giving a few of their tutorials a read and immersing yourself in the material.
