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.
- Itʼs primary use in modern computing is on Mac OS X as a desktop language and also on iPhone OS (or as it is now called: iOS).
- It was originally the main language for NEXTSTEP OS.
