What are the best resources for an experienced programmer looking to pick up up ObjC and iOS? I'm specifically not looking for 'in-24-hours' or 'without-writing-a-line-of-code' type things, nor screen casts or video lessons. Thanks!
I learnt a lot from the Stanford online courses on ITunes U. Granted they are video lessons, but you can also grab all the lecture notes and sample code from this link:
Other than that I just googled the hell out of things, Stack Overflow was, as always, a valuable resource. Chances are that whatever you're trying to do, particularly when learning, somebody else has already done.
If you've never programmed in C, you may want to seek out a good C tutorial. You can get pretty far in iOS working only with Objective-C objects, but plenty of C-isms leak through so it helps to be familiar with pointers, structs, functions and memory management.
Objective-C isn't too hard to get up to speed with, especially if you've ever worked in both C and a dynamic language like Python or Ruby. Wrapping your head around Cocoa Touch is a little more daunting, but Sadun's book does a good job of building up the basics step by step, then providing chapters on specific frameworks you can page-fault in as needed.
