Basic Sensors in iOS

Acknowledgments

Everyone has one book in them. This is my second, or depending how you want to look at it, my Platform 9¾, since this book, along with the other three forthcoming short books on iOS and sensor technology, will form the bulk of Programming iOS4 Sensors, which would probably be classed by most as my second real book for O’Reilly.

At which point, I’d like to thank my editor at O’Reilly, Brian Jepson, for holding my hand just one more time. As ever his hard work made my hard work much better than it otherwise would have been. I also very much want to thank my wife Gemma Hobson for her continued support and encouragement. Those small, and sometimes larger, sacrifices an author’s spouse routinely has to make don’t get any less inconvenient the second time around. I’m not sure why she let me write another, perhaps because I claimed to enjoy writing the first one so much. Thank you Gemma. Finally to my son Alex, still too young to read what his daddy has written, hopefully this volume will keep you in books to chew on just a little longer.
