The following books are almost a must for anyone interested in developing applications for IOS. Beginning iPad Application Development by Wei-Meng Lee. A Wrox publication Chapters ~ $42.00 Wrox Programmer to programmer. Learn Objective-C on the Mac by Mark Dalrymple | Scott Knaster a Apressbook. Chapters ~ $40.00 Of course you need a Mac and must copy down latest Xcode development software which provides API etc and structure for code development. Eventually you will need an Apple IOS device to test your app beyond the simulator provided in Xcode. I hope there is enough info here to help aspiring app developers get started. ------ End of Forwarded Message
