ViewController

Introduction to iOS App Design Patterns §

• A Fat View Controller is often referred to when a UIViewController becomes bloated.

• The responsibilities of a UIViewController are defined as follows:

  • Updating the content of Views in response to data changes.
  • Responding to user interactions.
  • Managing layout.
  • Coordinating with other objects.

• Only these four responsibilities are defined.

  • Other functionalities should be properly delegated to separate objects (obviously).
