Understanding MVC pattern used in iOS apps

Question

I have read Apple\'s MVC article and am confused about various things. Firstly Apple uses a combination of the View and the Controller in almost all its sample applications whi

Answer 1

• The model is the brain of the application. It does the calculations and creates a virtual world for itself that can live without the views and controllers. In other words, think of a model as a virtual copy of your application, without a face!

• A view is the window through which your users interact with your application. It displays what’s inside the model most of the time, but in addition to that, it accepts users’ interactions. Any interaction between the user and your application is sent to a view, which then can be captured by a view controller and sent to the model.

• Controllers in iOS programming usually refer to view controllers. Think of view controllers as a bridge between the model and your views. They interpret what is happening on one side (what the user does on the view side, or the information provided by the model) and use that information to alter the other side as needed.
