Welcome to Objective-C Programmer’s Reference. This is a book targeted at developers who have prior experience with other languages such as Java, Python, Ruby, or C++ and would like to leverage that knowledge into the Objective-C world.
Maybe you have played with the iPhone and would like to know how to develop that app that you wish were available on the AppStore. Or maybe you want to create a new desktop application in Mac OS X. Still, you may want to program in Objective-C just because you need to support iOS devices at your company. Whatever the reason, this book will help you to move from knowing concepts of programming in other languages to learning how to and (I hope) enjoying programing in Objective-C.
