Can anyone give me a simple explanation of how to implement twitter's OAuth in an iPhone app

I've found a handful of libraries, which claim to be plug'n'play, but without understanding how OAuth even works, I am not confident in my ability to fix any bugs that arise.

Could someone please just give me an OAuth开发者_JAVA技巧 For Dummies lecture here?

http://oauth.net/code/ scroll down to Objective-C

also here is some code http://github.com/bengottlieb/Twitter-OAuth-iPhone

check http://www.getsharekit.com/install/ it is open source code i guess.

They have implemented twitter using oAuth

Yahoo provides a flowchart that helped me understand how OAuth works:
