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.
