Note: This book was previously part of the Take Control series (covering iOS 4 and then iOS 6. My friends Adam and Tonya Engst can produce a limited number of high-quality ebooks each year, and they couldn't fit a revision of this title. With their permission and support, I revised the title myself, and turned to Jeff Carlson for technical and copy editing, and Scout Festa for proofreading. Christa Mrgan designed the cover graphic, and Michael E. Cohen provided expert advice on tuning the EPUB edition.
