You are going to love this book! I know I do, and I had to read every word of it and check every line of code, twice!! If you're like me, you've registered as an iPhone developer with Apple, read some docum- tation, and sought help in taking the next bold step. Perhaps you've picked up "Beginning iPhone Development," dutifully working through all of the projects, and you understood most of it. If not, I heartily recommend it. The book is great because it gently guides you through many of the technologies that make up an iPhone application. Make no mistake; the book covers a lot of ground. But the projects are kept relatively simple to keep the l- sons focused. First step taken, now boldly onward into the fray! This book picks up where "Beginning iPhone Development" leaves off. The projects herein were developed specifically for this book, but these are no lightweight applications. Some projects are based on shipping products, showing how various technologies are integrated into a cohesive application. Other projects cover difficult topics and thus are more focused.
