Using Location Services
Although this book is essentially about augmented reality, programming maps and location services make up a lot of the fundamental aspects needed for a successful AR application. In this chapter, we will look at the mapping capabilities of iOS and some advanced techniques to integrate these services within your AR application.
If you were just too excited to move ahead and skipped Chapter 2, I would recommend that you go back and take a quick peek at the section called “Detecting Location Capabilities.” It covers how to make sure location services are available and how to prevent your app from attempting to access services that the user might have disabled. If you're ready to dive in, let's get started.
