ptg ptg Praise for Developing Hybrid Applications for the iPhone “For those not ready to tackle the complexities of Objective-C, this is a great way to get started building iPhone apps. If you know the basics of HTML, JavaScript, and CSS, you’ll be building apps in no time.” —August Trometer, Owner of FoggyNoggin Software, www.foggynoggin.com “Lee S. Barney takes the complexities of iPhone application creation and utilizes simple and often witty examples and language to make this book an enjoyable and useful read. It is not a simple how-to book, but if you have some web programming background and an idea, this book can provide you with the foundation for well-made, maintain- able, and useable applications for the iPhone.” —William Dalton “This is an outstanding book! If you are interested in building applications for the iPhone, this is the book for you. Lee S. Barney makes it simple and easy to understand. He has you creating a custom application from the very first chapter.Then, he brings you up the learning curve until you’re building applications with advanced iPhone features, such as the accelerometer, GPS, and embedded maps.This is an extremely well-written and easy-to-follow book.” —Joey Skinner, CEO and President, Rodeo Software “Lee S. Barney employs his solid background in JavaScript and Xcode to demonstrate useful techniques for building hybrid iPhone applications. I appreciate his candor as he shares some of the pitfalls that might trap newcomers, which then supports the direction for his solution. If you have a strong background in Javascript and are looking to break into iPhone application development, this book would make for a good segue.” —A.
