which is the best design pattern in objective c?

please specify useful links to see before we go to dive to code!!!!!

because everytime while i go to dive straight to code i confused at middle of some point.To clear this we have to make first design then we can implement them.

Design patterns are many and no one is the best. They typically solve different problems in different domains. You can check out the book Cocoa Design Patterns, it should provide enough text and code to help you choose which pattern you need to use for your problems. :-)
