I normally spend so much time cranking out tutorials that I never stop to organize things. So, here I will layout a complete Web Design Tutorial.
When I say complete I really mean complete. I’ve created over 76 videos on HTML, CSS, XML, xHTML, PHP, MySQL, JavaScript, JQuery, and AJAX among other subjects.
All of the code I use in the tutorials is also free to use under the GNU license. That basically means you can do anything you like with it as long as you don’t sue me 🙂
Learn Objective C Part 1
In this tutorial I will begin by explaining Object Oriented Programming using Objective C. If you would prefer to read the article click on Learn Objective C Tutorial, otherwise watch the video below.
Object Oriented Programming with Objective C
In a previous article, I explained how you create object’s, instance variable’s and method’s in Objective C. In this article, I’ll explain Inheritance, Polymorphism and go over other OOP topic’s I missed previously.
Briefly, Inheritance provide’s you with a way to build additional capability’s onto existing class’s.
Polymorphism is a little more complicated. It allows you to call a parent object method and it will sort out which class object method should be executed.
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.
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.
