Hi all, I'm soon to be finished with reading the excellent Big Nerd Ranch book on learning Objective-C. It targets Xcode 4.2 and touches on iOS 5 as well. Now, where do I go from here if I want to read a structured book and not tutorials on the web? As I've read, the iOS book from Big Nerd Ranch is outdated and difficult to work with if you have iOS 5 & Xcode 4.2 in mind. I'd really like a book that is up-to-date. Can anybody recommend a book that would continue where the one on Objective-C left off? Thank you!
