--[b]What’s a framework? [/b]We’re glad you asked. A framework is a collection of parts—headerfiles, libraries, images, sounds, and more—collected together into a single unit. Apple ships technologies such as [b]Cocoa, Carbon, QuickTime, and OpenGL as sets of frameworks[/b]. Cocoa consists of a pair of frameworks, Foundation and Application Kit (also known as AppKit),along with a suite of supporting frameworks, including Core Animation and Core Image,which add all sorts of cool stuff to Cocoa.
