Developing iOS Applications with Flex 4.5: Build iPhone and iPad Apps with Adobe AIR and ActionScript 3 by Rich Tretola

Introduction

For Indian developers and students aiming to break into the world of iOS app development using familiar tools, Developing iOS Applications with Flex 4.5 by Rich Tretola offers a practical, project-driven path. Published by O'Reilly Media, this hardcover edition is a valuable resource for those who already know ActionScript 3 and want to build native-feeling apps for iPhone and iPad using the Adobe AIR runtime and the Flex 4.5 framework. Instead of starting from scratch with Swift or Objective-C, this book shows you how to leverage your existing skills to create polished, functional iOS applications — a perfect fit for Indian developers looking to enter the mobile app market quickly.

Book Overview

This book is a hands-on guide that takes you from a simple 'Hello World' application to complex interactions with the full range of iOS device capabilities. You will learn to use Flash Builder 4.5 to create and debug a Flex Mobile project, choose the right layout options, and understand how to work with native iOS features like the accelerometer, GPS, camera, photo gallery, and multitouch display. Throughout the chapters, you will build real-world examples that demonstrate how to read and write text files, use SQLite databases for local storage, interact with the web browser, make phone calls, send emails and text messages, and load web content using StageWebView. The book also covers designing for iOS with specific UI elements while maintaining a single codebase.

Key Highlights

• Leverage ActionScript 3 skills to create iOS apps without learning a new language.
• Step-by-step guidance from basic setup to advanced device API integration.
• Complete code examples for accelerometer, GPS, camera, gallery, and multitouch.
• Local data storage using SQLite and file I/O.
• Communication features including calls, emails, SMS, and browser interaction.
• UI design tailored for iOS while keeping a single Flex codebase.

Inside the Book

Early chapters focus on setting up your development environment with Flash Builder 4.5, creating a new Flex Mobile project, and understanding the automatically generated files. Later chapters dive deep into each iOS API, with clear explanations and ready-to-run code snippets. You will learn how to capture photos, read device orientation, access location data, and respond to touch gestures. The book also covers practical tasks like saving user preferences, creating a local database, and integrating with the phone's native communication apps. Each chapter ends with a summary and suggestions for further exploration.
