Yep, that title says 24 DAYS, not hours. You can’t learn a programming language in 24 hours. Publishers say you can, but that’s just for marketing purposes. To really learn a language -- to the point where you don’t have to look back through a book every other line -- takes time. It takes time to do the exercises. It takes time to formulate questions, and answer them for yourself (although I’ll be glad to answer any to the best of my ability). It takes time to let the language sink in.
I’m starting a series that will attempt to teach the Objective-C language. As Stephen Kochan did in his book, I will attempt to teach plain C and Obj-C as one language. I don’t know how long it’ll take to complete -- we’ll see. I want to do a solid job of teaching the language though. This post will be updated as an index of all the lessons. I hope to have the first one out by the end of the week.
My goal is to teach the series at a comfortable pace for most people. I want it to be a fun and engaging experience, and an easy place for beginners to begin their coding journey. As always, comments and criticisms are appreciated.
Download a copy of Xcode, and get ready to learn!

As I mentioned before, I will attempt to teach C and Objective-C as one language. Obj-C is a strict superset of plain C, which means that any valid C is also valid Obj-C. The reason for this decision is that C is a procedural language, where you worry about how you do a task, whereas Obj-C is an object-orientated language, where you worry about what you use to do a task. It’s a radical shift in mindset. As a result, although Obj-C builds smoothly off of plain C, not all C styles and procedures work with Obj-C.

I want to engage, not just present the facts. As a result, I will supply plenty of screenshots, and include exercises at the end of each lesson. I will also post the source code to each lesson on this blog.

I want to create a solid understanding that frees you from having to go back to a reference every other line of code. That gets annoying, and you won’t get much respect in programming circles. :P

I want to make it an easy and fluid learning environment. People learn better when they are subject to less stress. In fact, I’m not going to stress you at all—you’ll be your own motivator. You want to build the next great iPhone app -- so put in the effort! In this course, I hope to build up a small code library, and have each lesson build up off the previous.
