Programming in Objective-C, Third Edition (Developer's Library)

Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming for the iOS and Mac platforms.
The book makes no assumptions about prior experience with object-oriented programming languages or with the C language (which Objective-C is based upon). Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of object-oriented programming without having to first learn all of the intricacies of the underlying procedural language (C).
