12. Objects, Classes, Methods, and Messages in Cocoa Programming

Description: What is an object? An object is like a C struct: It takes up memory and has variables inside it. The variables in an object are called instance variables. So when dealing with objects, the first questions we typically ask are: How do you allocate space for one? What instance variables does the object have? How do you destroy the object when you are done with it?
13. Frameworks in Cocoa Programming

Description: A framework is a collection of classes that are intended to be used together. In other words, the classes are compiled together into a reusable library of code. Any related resources are put into a directory with the library. The directory is renamed with the extension .framework. You can find the built-in frameworks for your machine in /System/Library/Frameworks.

Description: Let's briefly discuss the chronology of an application: When the process is started, it runs the NSApplicationMain function, which creates an instance of NSApplication. The application object reads the main nib file and unarchives the objects inside. The objects are all sent the message awakeFromNib. Then the application object checks for events.
