The iPhone and iPad allow user positioning via multiple methods, including GPS. The growing number location-aware, and location-fenced, applications now arriving in the App Store make heavy use of these abilities. This book walks you through the basic tools you need to build geo-aware applications before diving into the available third-party geo-SDKs available for the iOS platform.
This short book is part of a collection that will, along with new material, be compiled into a larger book, iOS Sensor Programming. The other books in this collection are Augmented Reality in iOS, iOS Sensor Apps with Arduino, and Basic Sensors in iOS.
