APPLE FIRST OFFICIALLY ANNOUNCED the iOS 5 at the Worldwide Developers Conference (WWDC)
in June 2011. After 7 betas and with much anticipation, Apple finally rolled out iOS 5 with the
vastly improved iPhone 4S. With 200 new features added to the iOS, Apple is set to reign as the
king of the mobile platform for the foreseeable future. This means developers also have vast
potential for their applications — if you know how to program for the iOS platform. This book
will show you how.
When I first started learning about iPhone and iPad development, I went through the same journey
that most developers go through: Write a Hello World application, play around with Xcode and
Interface Builder, try to understand what the code is doing, and repeat that process. I was also
overwhelmed by the concept of a View Controller, and wondered why it was needed if I simply
wanted to display a view. My background in developing for Windows Mobile and Android did not
help much, and I had to start working with this concept from scratch.
This book was written to help jump-start beginning iPhone and iPad developers. It covers the
various topics in a linear manner that enables you to progressively learn without being overwhelmed
by the details. I adopt the philosophy that the best way to learn is by doing — hence, the numerous
hands-on “Try It Out” sections in each chapter, which first demonstrate how to build something
and then explain “How It Works.”
Although iPhone and iPad programming is a huge topic, my aim in this book is to get you started
with the fundamentals, help you understand the underlying architecture of the SDK, and appreciate
why things are done in a certain way. It is beyond the scope of any one book to cover everything
under the sun related to iPhone and iPad programming, but I am confident that after reading
this book (and doing the exercises), you will be well equipped to tackle your next iPhone or iPad
programming challenge. |
