Objective-C programming training course description

A hands on introduction that will allow you to master
Objective-C and start using it to write powerful native
applications for even the newest Macs and iOS
devices! Using The step-by-step approach, will let you
get comfortable with Objective-C's unique capabilities
and Apple's Xcode 5 development environment. Make
the most of Objective-C objects and messaging. Work
effectively with design patterns, collections, blocks,
foundation classes, threading, Git and a whole lot more.
Every session builds on what you've already learned,
giving a rock-solid foundation for real-world success!

What will you learn

Use Xcode 5.

Declare classes, instance variables, properties,
methods, and actions.

Use arrays, dictionaries, and sets.

Expand and extend classes with protocols,
delegates, categories, and extensions.

Use Apple's powerful classes and frameworks.
