Looping, Decision Making & Arithmetic Operation’s
In this article, I’ll review how to perform action’s repetitively with looping. I’ll then cover how to program decision making into your Objective C code. Finally, I’ll go over all of the arithmetic operation’s that are built into Objective C.
Data Type’s in Objective C
In this article I’ll go over all of the data type’s available to you with Objective C. They include:
In the previous article I gave you a brief overview of Object Oriented programming and showed you a little Objective C code. Objective C is the language used to program on all the Apple device’s and in this article you’ll learn a lot more about it.
Software you Need
To develop iPhone app’s you will need to download some free software from Apple. You get it online here: http://developer.apple.com/iphone/. It’s called the iPhone SDK and the current version is 3.2 as of this writing.
Here I begin my tutorial on iPhone, iPod Touch and iPad development. It’s surprisingly easy to develop for these device’s if you have a background in programming.
You must learn a new language to be able to develop anything on these device’s and that is Objective C. In this tutorial I will begin by explaining Object Oriented Programming using Objective C.
I wrote and taped a tutorial on OOP using JavaScript. I go into a lot of detail and give a bunch of example’s that explain OOP. You might want to watch / read that before proceeding?
