Geolocation in IOS

Take advantage of iPhone and iPad sensors and advanced geolocation technologies to build state-of-the-art location applications. In this concise hands-on guide, author Alasdair Allan (Learning iOS Programming) takes you deep inside Apple’s Core Location framework, Map Kit, and other iOS tools, using illustrative examples and sample Objective-C code. Learn how to build location-aware apps for both iPhones and iPads, using code that detects hardware features and then adjusts your app’s behavior. If you’re a programmer with iOS experience, or a Mac developer familiar with Objective-C, this book helps you get off to a solid start in location-based app development. You’ll learn about: Core Location: Understand the significant-change location service and geo-fencing capabilities Map Kit: Embed maps into your application’s views Magnetometer: Use the on-board sensor as a digital compass Geocoding capabilities: Translate geographic coordinates into place names, and vice versa Heat maps: Get a code walkthrough for displaying these maps on top of a standard MapKit view Third-party SDKs: Add unique geo-location capabilities to your app from SkyHook Wireless, MapBox, and other providers

iOS Sensor Apps with Arduino

Wiring the iPhone and iPad into the Internet of Things

Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you’ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You’ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time. iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low-cost project. If you're an Objective-C programmer who likes to experiment, this book explains the basics of Arduino and other hardware components you need—and lets you have fun in the process. Learn how to connect the Arduino platform to any iOS device Build a simple application to control your Arduino directly from an iPad Gather measurements from an ultrasonic range finder and display them on your iPhone Connect an iPhone, iPad, or iPod Touch to an XBee radio network Explore other methods for connecting external sensors to iOS, including Ethernet and the MIDI protocol
