| Welcome to your first lesson on Objective-C, the language used by Apple and Apple Developers to | |
| create iPhone, iPad, and Mac apps. Objective-C has been around since the early 80s and has an | |
| interesting history (according to Wikipedia). Basically, people wanted to have two things come | |
| together: the C programming language and Object-oriented programming. The result: Objective-C. | |
| In one corner we have classes and methods, and in the other we have hints and pointers. It's not | |
| the prettiest thing you'll ever see (though no one to date has ever died from reading Objective-C | |
| code). |
