Course description

This course provides an introduction into the basics of iOS programming using Objective-C. This course is ideal for a programmer who is familiar with other programming languages and wants to start developing for the iPhone and iPad. In this course, you will learn how to use the Xcode IDE to write code along with the built-in Interface Builder to drag and drop interface elements into views. We will cover how to work with Objective-C and Cocoa design patterns. You will learn how to use navigation and tab bar controllers and how to make your own table views to navigate data. Finally, we will discuss debugging and testing using Apples tools.

Prerequisites

A general understanding of programming using Xcode on a Mac.
