Hillegass cocoa programming for mac os x 4th edition
I read the third edition of Aaron Hillegass's book, and it was very consise and a great learning tool.
I have just bought the fourth efition, but have not started it yet, as I am on a iOS book at the moment, but after a quick flick through it, it seems that it is very much the same as the third edition, but has been updated for Xcode 4 and ARC, so I would recommend any of the Big Nerd Ranch Books.
The bad review on Amazon was written by a beginner programmer, who states that the code on page 21 was wrong and did not work, unfortunatley for that peson they got it wrong, as they where copying code from a screen shot, that was not intended as a code snippet, but as a screen shot showing something in the Xcode IDE, after this one bad experience after only 21 pages, he lost the plot and slated the book on an Amazon review.
I think that guy needs to slow down and take his time.
