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, yours"ll be building apps in no time." -August Trometer, Owner of FoggyNoggin Software, www.foggynoggin.com Discover the Easier, Faster Way to Build High-Quality iPhone Applications Now, you donrs"t need to dive headfirst into Objective-C to write state-of-the-art applications for the iPhone. You can use web development tools and technologies you already know: JavaScript, HTML, and CSS. In this book, long-time web and mobile application developer Lee S. Barney shows you how to use the QuickConnect and PhoneGap frameworks to create secure, high-quality, modular hybrid iPhone applications. Lee S. Barney walks you through the entire hybrid iPhone development process, from creating great user interfaces to compiling, deploying, and executing applications. Along the way, he introduces techniques and sample code designed to streamline development, eliminate complexity, optimize performance, and leverage all iPhoners"s native capabilities-from its accelerometer and GPS to its built-in database. Coverage includes Using Dashcode and Xcode together to create unique, exciting hybrid iPhone applications Using the QuickConnect JavaScript API to perform tasks ranging from vibrating the phone to accessing the accelerometer and GPS location data Accessing native iPhone functionality using the PhoneGap JavaScript API Storing, retrieving, and managing data on the iPhone, even without network access Using XMLHttpRequest to access or synchronize remote data and use web services Creating Google-based maps for your own app that work like those you see in the iPhoners"s Maps application This book systematically lowers the barriers to iPhone development, enabling web developers to build any iPhone application they can imagine without long development cycles or steep learning curves!

Lee S. Barney (Rexburg, Idaho) is a professor at Brigham Young University—Idaho in the Computer Information Technology Department of the Business and Communication College. He has worked as CIO and CTO of @HomeSoftware, a company that produced web-based, mobile data, and scheduling applications for the home health care industry. Prior to this, he worked for more than seven years as a programmer, senior software engineer, quality assurance manager, development manager, and project manager for AutoSimulations, Inc., the leading supplier of planning and scheduling software to the semiconductor industry. He is the author of Oracle Database AJAX & PHP Web Application Development.

Creating Hybrid iPhone Applications with JavaScript
Introduction
Hybrid application runs on the phone but is built in JavaScript
Hybrid applications are not mini web browsers
Hybrid applications use standard iPhone UI components
Tools and Modularity make hybrid application creation easy
Developing with Dashcode and Xcode Hybrid application creation makes use of both Dashcode and Xcode
Dashcode is used for creating the user interface and JavaScript creation, editing, and debugging, and Xcode is used for compiling, deploying, and executing the application on the device
This chapter discusses and gives examples of how these two tools can effectively be used together to develop hybrid applications without burdening the developer

JavaScript Modularity in iPhone Applications This chapter shows the reader how to create and use modularity in JavaScript to quickly and easily create dynamic iPhone hybrid applications
Modularity
What is modularity?
Tight cohesion
Loose coupling
Why modularity?
Eases development
Eases support
Division of labor
Business control functions in JavaScript
Purpose
Encapsulate decision making
Handles one or few decisions
Should data be retrieved?
What data should be retrieved?
Forward reference to Chapter 3
Example
Retrieving user information
Source code example and description
View control functions in JavaScript
Purpose
Encapsulate screen updating
Code becomes reusable for multiple commands
Handles updating one or more portions of the screen
Multiple VCF can be used for one command
Example
Displaying user information
Source code example and description
Command - response behavior
Linking BCF's and VCF's
Dispatching
One BCF per command
Multiple VCF's per command
Command validation
Validation must happen prior to dispatching to BCF's and VCF's
Multiple Validation functions per comma
