Back To Basics: Intro to Object Oriented Programming

If you’re our long time follower, you know we’ve gone pretty far. By now, you should be able to build an iPhone app with tab bar, navigation controller and table view using Storyboard. One request on the top of my list, however, is to enhance the detail view of the Recipe app. Many readers mentioned the original detail view is too plain. How can we display more information including an image? That shouldn’t be difficult if you understand the materials and I intentionally left out that part for you at the time I wrote the tutorial. :-)

Did you manage to create your own detail view for the Recipe app? Anyway, we’ll revisit it and show you how to improve the detail screen. But before that, I have to introduce you the basics of Object Oriented Programming. In the next tutorial, we’ll build on top of what we learn in this tutorial and enhance the detail view screen.

Don’t be scared by the term “Object Oriented Programming” or OOP in short. It’s not a new kind of programming language but a programming concept/technique. I intentionally left out the OOP concept when I first began writing the iOS programming tutorials. I want to keep thing simple and show you (even without any programming background) how to create an app. I don’t want to scare you away with technical term. However, I think it’s time to cover the concept. If you’re still around reading this article, I believe you’re determined to learn iOS programming and you want to take your app to the next level.
