Understanding the Model-View-Controller Paradigm

When you start programming, you’ll quickly come to the conclusion that there is more than one “correct” way to do just about everything. Part of the joy of programming is that it is a creative process in which you can be as clever as your imagination allows. This doesn’t mean, however, that adding structure to the development process is a bad idea. Having a defined and documented structure means that other developers can work with your code, projects large and small are easy to navigate, and you can reuse your best work in multiple applications.

The application design approach that you’ll be using in iOS is known as Model-View-Controller (MVC), and it can help you create clean, efficient applications.
