Good quick refresher and jumping off point for getting my feet wet in iOS programming. Current as of a couple of months ago, as I write this. Covers the newest changes to iOS 5 and Xcode. I'll probably continue to refer to it until I get really comfortable with what's new in Objective-C 2.0. The full colour screenshots, although unnecessary, were a nice addition.
Takes the same approach as a lot of these kinds of books do. It shows the reader the long way or the wrong way to do something, and then has the reader undo that work and show the quicker or more correct way to do something. For the experienced programmer, such as myself, who's merely trying to get up to speed in Objective-C, I found that a little annoying, but I also understand the reason why, so I don't hold it against the author.
The only cons are that the ink is a little smelly, and the pages are quite thin. I was worried at first that I might easily tear them while flipping through the book. That hasn't happened yet, though.
