Time for action — adding Augmented Reality to your iPhone app
Download the Layar Player SDK from http://www.layar.com/player/ and set up your existing app by importing the required libraries into your Xcode project. For this example, let's name it Hello Events-Augmented Reality. Follow the documentation available with the SDK to configure your project; read more about this at http://layar.pbworks.com/w/page/35051901/Layar-Player-on-IPhone. The sample code will be available on the book's site, so you can use the project template to play around with.
