difference between creating an iphone app & mac os app

I am an iphone/ipad apps developer.Now I also want to creat开发者_开发知识库e mac apps. I wanted to know that how should I start learning mac app development. I started by creating the Currency converter app in the apple docs.But that is quite simple. I wanted to explore about the different controls for mac app. Please guide.

Much of your basic Obj-C/Cocoa knowledge (Foundation.framework-related stuff) will directly translate. The primary difference is UIKit vs. AppKit for the UI. The overall controller-layer architecture also has some differences (view-controller specific stuff).

To explore the controls, open Interface Builder, create a plain Cocoa Application xib and start exploring the controls by dragging them into a window. Use the API reference as your guide.

Happy coding.
