Beginning iPad Development for iPhone Developers (eBook)

Jack Nutting has been using Cocoa since the olden days, long before it was even called Cocoa. He has used Cocoa and its predecessors to develop software for a wide range of industries and applications, including gaming, graphic design, online digital distribution, telecommunications, finance, publishing, and travel. When he is not working on Mac or iOS projects, he is developing web applications with Ruby on Rails. Nutting is a passionate proponent of Objective-C and the Cocoa frameworks. At the drop of a hat, he will speak at length on the virtues of dynamic dispatch and run time class manipulations to anyone who will listen (and even to some who won t). Nutting is the primary author of Learn Cocoa on the Mac (Apress, 2010) and Beginning iPad Development for iPhone Developers (Apress, 2010). He blogs from time to time at Nuthole.com.
