Designing software architecture is usually the first step in the implementation process. This presentation steps through several important design patterns with examples of how they are used.

Here are some of the patterns that are presented:
- Singleton
- Decorator
- Iterator
- MVC
- Proxy
- Facade
- Abstract Factory
- Factory Method
- Object Pool (UITableViewCell: prepareForReuse and dequeueCell)- Lazy Initialization
- Lazy Initialization
Others
- Data Hub
- Blackboard (Facade over NSNotificationCenter)
- State

To demonstrate these patterns, some interesting examples are used:
- Generating a PDF using Core Graphics in iOS
- Fast Enumeration, blocks and Encapsulation
- Inheritance and Polymorphism
- UIWebView layers and using delegation and the main thread
