Chapter 3. Objective-C Once upon a time, a man named Brad Cox decided that it was time for the world to move toward a more modular programming style. C was a popular and powerful language. Smalltalk was an elegant untyped objectoriented language. Starting with C, Brad Cox added Smalltalk-like classes and message-sending mechanisms. The result, Objective-C, is a very simple extension of the C language. In fact, Objective-C was originally simply a C preprocessor and a library. Objective-C is not a proprietary language.
For example, to add objects to the end of the array, you use the addObject: method (assume that bar is a pointer to another object): [foo addObject:bar]; If you have multiple arguments, the selector will have multiple parts. For example, to add an object at a particular index, you could use the following: [foo insertObject:bar atIndex:5]; Note that insertObject:atIndex: is one selector, not two. It will trigger one method with two arguments. This outcome seems strange to most C and Java programmers but should be familiar to Smalltalk programmers.
