I DO NOT recommend this book at all for any level of iPhone developer(s).



One of the projects actually just takes an Apple code example and adds a few methods here and there. I don't have to buy a book to do that. One project adds some methods and ivar's to files that are generated files per Core Data. This is always a bad idea.



There are many mistakes in the source code in the book. The source code in the book doesn't match the downloadable source code in many places. The downloadable source code fails to build and is missing files. I found such obvious errors in the downloadable source like no semicolon at the end of some of the lines. This code was obviously never built and/or tested.



This book was very poorly and hastily put together. Don't waste your money, but more importantly, don't waste your time.
