Cocoa in a Nutshell
Cocoa is a great thing to learn, and if you've got some relevant experience with other languages, this book is a great way to learn it. It's one of the Apple Developer Connection recommended O'Reilly titles, and comprises a complete and thorough reference to the language that most Cocoa developers will appreciate.
I say most Cocoa developers rather than all of them because this is of course a Nutshell handbook - it's not intended to serve as a step-by-step tutorial for those without any prior Cocoa or object-oriented programming experience (for that, there's Learning Cocoa with Objective-C). Readers completely unfamiliar with the language may find the book a little bewildering, it's true. However, that's not to say you need to have already mastered the language before picking up the Nutshell book - the first part contains quite a decent introduction, and if you're already familiar with something like Java, this will probably be all you need. I have a couple of years of experience with C and Java myself, and although this was my first Cocoa book, I didn't feel lost when reading the book's first half.
Coauthor Michael Beam notes that "The 'In a Nutshell' format had always been a very efficient means of communicating information, particularly for more experienced developers. Cocoa is a very verbose and wordy API; that is, the method names are long and can have many arguments. It is often the case that a developer can be moving along in his code, and he knows what method to use, but can't remember the precise syntax. This book seeks to provide a quick way to look up that syntax." I think that's a goal it achieves admirably, and as long as readers are aware they're buying a reference and not a gentle introduction to programming, they won't be disappointed.
It's primarily the second half of the book that serves as a complement to Apple's documentation for the Foundation and AppKit classes. Apple's Cocoa site is better than it used to be, and it does include a basic API Reference along the line's of Sun's site for the Java API - you can use it for the kind of syntax-checking Beam is talking about, and many developers do just that. If you're already in the habit of looking things up on the Apple site, the API documentation in this book won't change your life. I prefer it to the web version, partially because there's slightly more explanation of the various classes, but not everyone will feel the same way.
So, who should buy this book? The intended audience is pretty much the same as that of the other programming-related Nutshell books. If you're completely new to programming, don't bother. You'll be much better off starting with something that assumes no knowledge of programming concepts and skills. On the other hand, if you're an experienced Cocoa developer who'd rather use Apple's Cocoa site than shell out for a book, there's really no reason to do so. But plenty of people don't fall into either of these categories. If you've got some OOP experience, and especially if you've already fumbled your way through a little bit of Cocoa but would like to learn more, you'll find the overview section very useful and the reference section convenient. (It's probably also worth noting that, at least at the moment, Amazon is offering Cocoa in a Nutshell for $15.98, down from $39.95. Even if you're not totally convinced it's worth forty bucks, it's definitely worth sixteen.)
