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.

The Marco window

Now that our players can push their location to the Cloud, we can retrieve those same locations and display them on a map view using annotations (pins). There is not much code needed for the user interface, since the only component is a map view that will occupy the entire screen's real estate.

Creating a dedicated map module

Just as we did with the GeolocationService variable, we will isolate all the code related to mapview into its own file for more clarity. We will create a new file named Map.js into our Resources directory and create two functions in it.

The first function will be named createMap, which will return a new mapview variable. It will be of standard type, meaning that it will display a street map with street names, for example. It will use a smooth animation when the map region changes and will adjust its aspect ratio to fit the region using the regionFit property. Also, we want to show where the player is located on the map by setting the userLocation property...
