It seems as if everyone is writing applications for Apple’s iPhone and iPad, but how do they all do it? It’s best to learn Objective-C, the native language of both the iOS and Mac OS X, but where to begin? Right here, even if you’ve never programmed before!
Objective-C for Absolute Beginners will teach you how to write software for your Mac, iPhone, or iPad using Objective-C, an elegant and powerful language with a rich set of developer tools. Using a hands-on approach, you’ll learn to think in programming terms, how to use Objective-C to build program logic, and how to write your own applications and apps.
With over 50 collective years in software development and based on an approach pioneered at Carnegie Mellon University, the authors have developed a remarkably effective approach to learning Objective-C. Since the introduction of Apple’s iPhone, the authors have taught hundreds of absolute beginners how to develop Mac, iPhone,and iPad apps, including many that became popular apps in the iTunes App Store.
What you’ll learn
- The fundamentals of computer programming: how to understand variables,design data structures, and work with file systems
- The logic of object-oriented programming: how to use Classes, Objects, and Methods
- The flexibility of Apple's developer tools: how to install Xcode and write programs in Objective-C
- The power of Cocoa and Cocoa touch: how to make Mac OS X applications or iOS apps that do cool stuff
Who this book is for
Everyone! This book is for anyone who wants to learn to develop applications for the Mac or apps for the iPhone and iPad using the Objective-C programming language. No previous programming experience is necessary.

On page 41:Original : For example, the hexadecimal number 2AF3 is equal, in decimal to (2 x 16³) + (10 x 162) + (15 x 161) + (3 x 160)
In the last three expressions of the calculus, the numbers should be multiplicated by powers of 16.
Correct :
decimal to (2 x 16³) + (10 x 16²) + (15 x 16¹) + (3 x 16⁰)
On page 99:
On page 99 it says "The third line:

current reads - >
- (void)setTitle(NSString* newString);

In code review and full code example
line
NSDate *saleDate = [NSDate dateWithString:@"2010-0 9–04 04:00:00 -0700"];
date format is (YYYY-MM-DD) you made a mistake when you put "-0" at end on the year
It should read:
NSDate *saleDate = [NSDate dateWithString:@"2010-9–04 04:00:00 -0700"];
On page 171:
line:
NSMutableArray *bookList = [NSArray arrayWithObjects:@"Moby Dick", @"Frankenstein",
@"Tom Sawyer”, nil];
should be:
NSMutableArray *bookList = [NSMutableArray arrayWithObjects:@"Moby Dick", @"Frankenstein",
@"Tom Sawyer”, nil];
On page 172:
an NSMutableDictionary
code example:
NSMutableDictionary *book;
