For anyone who actually wants to build an app -- This guide is very long winded. For iOS, the easiest way is to download xCode and try to build it.

I would suggest Aaron Hillegass' Big Nerd Ranch Guides for ObjC and iOS programming. I read those books over a few days to get started and felt as though they provided a great foundation for all ObjC things to come. Stack Overflow fills in the blanks.

You don't have to take my advice, but it's been 8 months since I started "building my killer app", it's been out in the app store for almost 5 months, and since then we've been featured by Apple, and have over 50K users. Just plan to start what you've finished and you'll force yourself into having a killer app.

I love the Big Nerd Ranch! That's definitely a great way to learn, but if you want more than just a book to work from, that's where Treehouse is here to help (Big Nerd Ranch has AWESOME bootcamps, too). It's so exciting to have so many great resources available cheaply or freely.
