Erica Sadun - The iOS 5 Developers Cookbook: Core Concepts and Essential Recipes for iOS Programmers

This book would be a bargain at ten times its price! If you are writing iPhone software, it will save you weeks of development time. Erica has included dozens of crisp and clear examples illustrating essential iPhone development techniques and many others that show special effects going way beyond Apples official documentation.

Tim Burks, iPhone Software Developer, TootSweet Software

Erica Saduns technical expertise lives up to the Addison-Wesley name. The iPhone Developers Cookbook is a comprehensive walkthrough of iPhone development that will help anyone out, from beginners to more experienced developers. Code samples and screenshots help punctuate the numerous tips and tricks in this book.

Jacqui Cheng, Associate Editor, Ars Technica

We make our living writing this stuff and yet I am humbled by Ericas command of her subject matter and the way she presents the material: pleasantly informal, then very appropriately detailed technically. This is a going to be the Petzold book for iPhone developers.

Daniel Pasco, Lead Developer and CEO, Black Pixel Luminance

The iPhone Developers Cookbook should be the first resource for the beginning iPhone programmer, and is the best supplemental material to Apples own documentation.

Alex C. Schaefer, Lead Programmer, ApolloIM, iPhone Application Development Specialist, MeLLmo, Inc.

Ericas book is a truly great resource for Cocoa Touch developers. This book goes far beyond the documentation on Apples Web site, and she includes methods that give the developer a deeper understanding of the iPhone OS, by letting them glimpse at whats going on behind the scenes on this incredible mobile platform.

John Zorko, Sr. Software Engineer, Mobile Devices

Ive found this book to be an invaluable resource for those times when I need to quickly grasp a new concept and walk away with a working block of code. Erica has an impressive knowledge of the iPhone platform, is a master at describing technical information, and provides a compendium of excellent code examples.

John Muchow, 3 Sixty Software, LLC; founder, iPhoneDeveloperTips.com

This book is the most complete guide if you want coding for the iPhone, covering from the basics to the newest and coolest technologies. I built several applications in the past, but I still learned a huge amount from this book. It is a must-have for every iPhone developer.

Roberto Gamboni, Software Engineer, AT&T Interactive

Its rare that developer cookbooks can both provide good recipes and solid discussion of fundamental techniques, but Erica Saduns book manages to do both very well.

I dedicate this book with love to my husband, Alberto,
who has put up with too many gadgets and too many
SDKs over the years while remaining both kind
and patient at the end of the day.

This book would not exist without the efforts of Chuck Toporek (my editor and whip-cracker), Chris Zahn (the awesomely talented development editor), and Olivia Basegio (the faithful and rocking editorial assistant who kept things rolling behind the scenes). Also, a big thank you to the entire Addison-Wesley/Pearson production team, specifically Kristy Hart, Anne Goebel, Bart Reed, Linda Seifert, Erika Millen, Nonie Ratcliff, and Gary Adair. Thanks also to the crew at Safari for getting my book up in Rough Cuts and for quickly fixing things when technical glitches occurred.
