Programming Paradigms Object-Oriented Programming Model-View-Controller Model-View-Controller ? Controller The controller receives user input and initiates a response by making calls on model objects. A controller accepts input from the user and instructs the model and viewport to perform actions based on that input Delegation Target-Action Notifications Objective-C Basics Language?
