Overview

This course is an introduction to iOS application development. It covers how to create and compile projects using Xcode, basics of the Objective-C language, memory management, delegation, Core Location, MapKit, text input, views, view controllers, notification center and rotation. After this, you will create a reasonably complex iOS program. In the process, it covers table view, table view controller, editing table view, navigation controllers, camera, popover and modal view controllers, saving and loading, application states, subclassing table view cells and Core Data.

Programs you will write:

Quiz - A quiz application that shows you a list of questions and provides the answers when the answers button is tapped.

RandomPossession - A command-line program that illustrates how to create and use a custom class.

Whereami - A map application that shows your location.

Hypnosister - A program drawing graphics on the screen.

Hypnotime - A program that shows how to use tab views.

HeavyRotation - A program that shows how to implement autorotation when the devices is rotated.

Homepwner - An asset tracking program that is able to display its contents in a table, allows editing of the data in the table, able to take and display photos of your assets, and able to load and save data.

NerdFeed - An application that can download and parse JSON objects from the web and display web content.
