Course Description

 
This Objective-C training class teaches the fundamentals of programming in Objective-C, the language used to develop iPhone and iPad applications. This course covers Xcode, the integrated development environment used to build Objective-C applications. Primitive and reference variables are covered as well as arithmetic operators, conditional processing, looping, and functions. The object-oriented nature of the language is presented as well as the Foundation framework. An introduction to the Cocoa framework and a discussion of a basic user interface for mobile devices are included. We will use Xcode built-in iPhone and iPad simulators for the exercises and demonstrations in the course. In this way, students get a feel for how iPhone and iPad application development works and will be ready to move on to our iOS Application Development class. This course has been updated for Xcode 6 and iOS 8.
