* Last part of chapter 7 reviews the other design patterns (besides MVC). Most significantly for me, is that the authors refer to protocols. I have been challenged by protocols in the past
* "When a framework object has been designed to use delegates to implement certain behaviors" (p 153 the behaviors it requires are defined in a protocol.
Protocols define an interface that the delegate object implements."
* Protocols can be formal or informal. If I use formal protorcols I only have to implement the methods that I need.
*Ways to customize an apps behavior with UIKit include:
•Subclassing
•Delegation
•Target-Action
•Block Objects
