Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming for Apple’s 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 C programming language.
Source Code:
Although the author states in the Introduction that ‘you won’t find the “official” source code for all the examples there, as I am a firm believer that a big part the learning process occurs when you type in the program examples yourself and learn how to identify and correct any errors,‘ but much of the Objective C source code from the book is available at classroomM.com/objective-c as part of community discussion forum on Programming in Objective-C.
