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.

Animating a view using 2D Matrix and 3D Matrix transformations


You may have noticed that each of our ImageViews in the previous recipe had a click event listener attached to them, calling an event handler named setChosenImage.

This doesn't exist, so you get an error if you click an image. Let's fix that. This event handler will handle setting our chosen funny face image to the imageViewFace component, before animating the four funny face ImageView selectors out of screen using a number of 2D and 3D Matrix transforms.

How to do it…

Replace the empty setChosenImage function at the bottom of the app.js file with the following code:

//this function sets the chosen image and removes the 4
//funny faces from the screen

function setChosenImage(e) {
  imageViewFace.image = e.source.backgroundImage;
  imageViewFace.visible = true;
  imageViewMe.visible = true;

  //create the first transform
  var transform1 = Ti.UI.create2DMatrix();
  transform1 = transform1.rotate(-180);
  transform1 = transform1...
