Key-Value Observing (KVO) is a design pattern related to KVC which allows you to build more complex applications. By de-coupling models and controllers, you can have a single model power many controllers, allowing larger applications without added complexities.

Objective-C Lesson 10: Memory Management
On any platform, specifically the memory-constrained iOS platform, memory management is an important topic to keep in mind.
