Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

At the top, we will find a text field where the users will enter their monetary objective. There will also be two more text fields (symbol and quantity) and a button used to add a new stock to the user's portfolio. All these text fields will be accompanied by labels next to them for clarity.

The lower section of the screen will be used to display the portfolio's stocks using a table view control. Also, at the very bottom of the screen, there will be a button that will allow to save all the settings, refresh the portfolio's data, as well as close the current window:

Coding what we have designed
