View Controllers: Role in iOS projects

Today here, we will be bouncing back to the basics and going to discuss the View controllers. Let us start with the basic introduction of the View controllers and their role in the iOS projects development.

The View controllers are the core part of any iPhone application development. They act as a bridge between your models and your views. View controllers are both responsible for fetching/initializing your models as well as loading the views to display the information they contain.

The basic View controllers

Every view controller that Apple provides extends from the base UIViewController subclass. This gives the iPhone programmers a few basic properties that they might find handy. The most important is the view property. This is the basic reference to the view that the controller is managing.

Here are some of the basic view controllers to be discussed in this post:
> UINavigationController
> UITableViewController
