The Objective-C language is a simple computer language designed to enable sophisticated object-oriented programming. Objective-C is defined as a small but powerful set of extensions to the standard ANSI C language. Its additions to C are mostly 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 straightforward 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 the development 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 .
