What exactly do you want to learn about? If it's just the basics of how to use Objective-C and Cocoa, try Apple's Introduction to the Objective-C Programming Language.

For everything Objective-C? http://developer.apple.com contains gigabytes of documentation about Objective-C, the Cocoa frameworks, and the secondary Objective-C-based frameworks on Apple's operating systems.

If it is a reference you are after, everything you need is in the Xcode/SDK download. The developer documentation menu item under Help provides access. However, I personally don't think the search is very good. If you are on line, you can Google developer.apple.com for the same docs. For example the search term:

site:developer.apple.com ios nsstring

will take you to the class reference for NSString.

Up and Running: Objective-C is what I used to cut my teeth on. Great book to get you started. All those Beginning iPhone books are worthless for teaching you Objective-C. Get a real Objective-C book and then start reading those other books. For $5 you can purchase the iOS ebook. Best $5 I have ever spent.
