iOS Architecture Guide

Model Objects should be dumb - minimal logic

Model Controllers should perform model manipulations that are UI independent (like network and processing) exception: user input 

No Story Boards

Implement classes with dependency injection - favor providing all data at instantiation

Code for iOS 6 - will back port to iOS 5 as necessary

When creating “updateUI” methods, pass an animated flag: ex. updateUIanimated:(BOOL)animated;

Constants should be defined in the file that uses them if possible (i.e. Notification constants should be defined in the header of the file that posts the notification)

When a notification is required, evaluate potential patterns in this order, selecting the highest rated viable pattern:
1. Blocks
2. Notification Center
3. Delegation
4. ReactiveCocoa
4. KVO (MAKVONotificationCenter)
