I found some brilliant discussion threads on learning C on HN, resulting in the purchase of the C Programming Language (2nd Ed) book and the C Puzzle Book, which I am working through at the moment. I've ordered C Interfaces and Implementations as well as The Practise of Programming, which should arrive shortly. As much benefit as I will derive from learning C, I'm interested in learning Objective-C, to allow me to write software for my Mac, as well as for iPhone, and therefore humbly ask if anyone has any recommendations for Objective-C books. I've found a Programming in Objective-C book written by Stephen Kochan for example, but wonder how good it is.
