Objective-C Essential Training 2013

There are a lot of programming languages out there, but Objective-C is the best choice for developers who want to develop iOS and OS X apps. This course is your primer. Get the tools you need, learn the structure of Objective-C, and get your first code up and running. Author Simon Allardice also walks you through the Foundation framework, a collection of prewritten code that makes the coding process easier; shows you how to design and build your own classes; and provides memory management techniques—the key to efficient programming. Plus, learn how to make your way around Xcode 5, the app to write, test, and debug Objective-C, and into advanced features like categories, protocols, and dynamic typing.

Topics include:

• Installing the tools
• Understanding the structure of an Objective-C program
• Logging messages and using format strings
• Writing conditional code
• Using code snippets
• Working with variables, classes, and functions
• Working with objects
• Using existing classes in the Foundation framework
• Managing memory usage
• Creating custom classes
• Working with Objective-C collections
• Reading and writing to files
• Understanding inheritance and NSObject
• Using Categories, Protocols, and Class Extensions
• Compiling and debugging code
