Overview of this book

This book will take you through the process of building cross-platform, native UI applications for the mobile from scratch. You will learn how to develop apps, how to use GPS, cameras and photos and how to build socially connected apps. You will also learn how to package them for submission to the App Store and Google Play. This cookbook takes a pragmatic approach to creating applications in JavaScript from putting together basic UIs, to handling events and implementation of third party services such as Twitter, Facebook and Push notifications. The book shows you how to integrate datasources and server APIs, and how to use local databases. The topics covered will guide you to use Appcelerator Studio tools for all the mobile features such as Geolocation, Accelerometer, animation and more. You’ll also learn about Alloy, the Appcelerator MVC framework for rapid app development, and how to transfer data between applications using URLSchemes, enabling other developers to access and launch specific parts of your app. Finally, you will learn how to register developer accounts and publish your very own applications on the App Store and Google Play.

Speeding up your remote data access with Yahoo YQL and JSON

If you are already familiar with using JavaScript heavily for the Web, particularly when using popular libraries such as jQuery or Prototype, then you may already be aware of the benefits of using JSON instead of XML. The JSON data format is much less verbose than XML, which means that file size is smaller and data transfer is much faster. This is particularly important when a user on a mobile device may be limited in data speed due to network access and bandwidth.

If you have never seen Yahoo!'s YQL console or heard of the YQL language web service, note that it is essentially a free web service that allows developers and applications to query, filter, and combine separate data sources from across the Internet.

In this recipe, we are going to use the Yahoo! YQL console and web service to obtain data from our recipes' data feed, and transform that data into a JSON object, which we'll then bind to our TableView.
