TheObjective-C language is a simple computer language designed to enable sophisticated object-oriented programming.Objective-Cis defined as a small but powerful set of extensions to the standard ANSI C language.Its additions to Caremostly based on Smalltalk, one of the first object-oriented programming languages.Objective-C is designed to give C full object-oriented programming capabilities, and to do so in a simple and straight forward way.
Most object-oriented development environments consist of several parts:
● An object-oriented programming language
● A library of objects
● A suite of development tools
● A runtime environment
This document is about the first component of thedevelopment environment— the programming language. This document also provides a foundation for learning about the second component, the Objective-C application frameworks collectively known as Cocoa. The runtime environment is described in a separate document, Objective-C Runtime Programming Guide.
