Objective-C is the language used by Apple and their developers to create iPhone, iPad and Mac apps and their respective application programming interfaces (APIs), Cocoa and Cocoa Touch. In fact, Objective-C is the primary programming language used to write software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime.
You can find an overview of Objective-C here.
If you’re comfortable with basic object-oriented concepts and the C language, Objective-C will make a lot of sense. If you don’t know C, you should read a C tutorial first. Here are 2 tutorials on what you should know about C in order to start programming in Objective-C:
Also, if you want to learn it step by step, here you can find 7 chapters of study in order to learn the basics of Objective C programming. This article http://teamtreehouse.com/library/objectivec-basics will walk you through:
- C language fundamentals and functional programming in C,
- Pointers and Memory, because C programming requires first hand knowledge of how memory is allocated and destroyed,
- Introduction to Objective-C,
- Foundation Framework, used to accelerate the development of an application.
