Tell me what is MVC and how is it implemented in iOS?
What are some pitfalls you've experienced with it? Are there any alternatives to MVC?
Answer:
MVC stands for Model, View, Controller. It is a design pattern that defines how to separate out logic when implementing user interfaces. In iOS, Apple provides UIView as a base class for all _View_s, UIViewController is provided to support the Controller which can listen to events in a View and update the View when data changes. The Model represents data in an application and can be implemented using any NSObject, including data collections like NSArray and NSDictionary.
