Chapter 1
This chapter summarizes the available sensors on the iPhone and iPad platforms
and how they could be used in applications. It talks about the differences between
the hardware platforms.
Chapter 2
This chapter includes a discussion on the Core Location framework, covering
standard location monitoring as well as the significant-change location service,
which provides a low-power way to get the current location and be notified of

changes to that location. It also covers region monitoring, which provides geo-
fencing capabilities on the platform.

Chapter 3
This chapter includes a discussion on the MapKit framework, which allows you to

embed maps directly into your application’s views, and provides support for an-
notating these maps.

Chapter 4
This chapter shows how to use the onboard magnetometer, which is present in
many iOS devices, as a digital compass using the Core Location framework.
Chapter 5
This chapter discusses the geocoding capabilities of the platform that allow you to
go from a latitude and longitude to a place name, and vice versa.
Chapter 6
This chapter walks through code that allows you to display heat maps on top of a
standard Map Kit view.
Chapter 7
This chapter points to more information and some of the available third-party

software development kits (SDKs) that make it easier to carry out geocoding, geo-
fencing, and real-time location streaming as part of your application.
