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.

One window to rule them all

Since we want to give our users the ability to post their messages on multiple social networks at once, it makes perfect sense to keep our whole application in a single window. It will be comprised of the following sections:

  • The top section of the window will contain labels and a text area for message input. The text area will be limited to 140 characters in order to comply with Twitter's message limitation. As the user types his or her message, a label showing the number of characters will be updated.

  • The bottom section of the window will use an encapsulating view that will contain multiple image views. Each image view will represent a social network to which the application will post the messages (in our case, Twitter and Facebook). But we can easily add more networks that will have their representation in this section. Each image view acts as a toggle button in order to select if the message will be sent to a particular social network or not.

  • Finally, in the middle...
