When you develop a program in Objective-C, you won’t be on your own. You’ll be drawing on the work done by Apple and others, on the classes they’ve developed and packaged in Objective-C frameworks. These frameworks give you a set of interdependent classes that work together to structure a part—often a substantial part—of your program.
This chapter describes what it’s like to write an Objective-C program using a Cocoa framework. It also gives you the basic information you need to know to make a subclass of a framework class.
