Even for people strictly interested in Objective C, Apple does have their ref guide (http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Introduction/chapter_1_section_1.html http://developer.apple.com/documentation/Cocoa/Conceptual/Ob...), and there is also a book not on cocoa but on objc the language called "Programming in Objective-C" by Kochan (which I do believe there's a second edition soon to go to print that would be a very good idea to wait for). I don't really think either one of them considered the reader to be a complete beginner or "retarded", although the former is probably more down-and-dirty with the language than the latter is, which is more of an introductory text. Who hasn't seen one of those for any language? If you want a retarded cocoa book, check out the older Mac programming-related texts O'Reilly used to publish a few years ago. Out of print now I think, but man, they REALLY assumed you were a complete beginner. Not that that was a bad thing, but Hillegass is definitely miles better.
