Acknowledgments
A book is one of those things that involves so many people besides the author listed on the cover This book would not exist without the hard work of all those individuals To all of the fine folks at Peachpit Press, thank you for your time and energy in this project.
Margaret Anderson, Nancy Peterson, and Jan Seymour read through my early writings and helped me turn them into the book you’re reading today Without their guidance and expertise in communication, this book would not have been possible
I am truly blessed to have worked with such a solid, professional, and savvy team
I hope to work again with all of them in the future Scott “Fish” Fisher, my tech editor, played an equally important role of double-checking my code samples to
be sure they were accurate, simple, and to the point Thanks, Fish.
For people not directly involved in this book, I want to thank the folks at Flipboard for their help answering questions Also, thanks to Charles Ying for reading some early drafts and serving as a test audience You guys are a top notch team and I love your work.
As a side note, I wouldn’t be where I am today without the teaching efforts of Evan Doll and Alan Cannistraro Thank you, guys.
Finally, I would like to thank everyone over at Kelby Media Group and those who use my apps iOS is a platform that is ever changing For this reason I am constantly learning and applying knowledge to new apps Kelby Media Group, specifically Scott Kelby and Dave Moser, have offered me so many opportunities
to continue to work with their team and perfect my craft To the fine users of NAPP who download my apps, thank you for your feedback Without users, an app developer’s life is pretty boring.
