preface

My professional coding career has gone from large to small in a variety of ways. I

started on 3279 terminals at

IBM

, and with each professional move (from Ericsson to

Travelocity and others) I went to smaller machines and smaller companies. Now I

work on computers you can fit in your pocket and at a company of one: me.

When I first started working in mobile development, I used

J2ME

on various

phones, including Blackberries. When I got the chance to work on an iPhone, I pur-

chased my first MacBook and loved it! It wasn’t until sometime later that I realized that

I had gotten in at the beginning of the mobile wave. Solving problems alone, and often

under non-disclosure agreements, I learned a lot, and as each new version of the

came out, it got easier and better. The platform quickly became more sophisticated,

and so did the user.

Then Manning approached me to talk about a book on i

development, and I

was surprised how clear and formed my opinions were about what should be included.

I had learned a lot on my own—from frameworks to widgets to the

MVC

and

more—and I felt that emphasis was often placed on the wrong areas. I also felt that

the sample code provided by Apple was underemphasized. I believe that project-based

learning is the best—at least it is for me—and seeing how the different parts of a proj-

ect come together is not only useful but necessary to make sense of the project and

put it into context.

I was flattered that Manning asked me to write this book and I hope it will help you

to learn i

development—and to put it into practice.

Roadmap

Part 1 covers the groundwork needed to get started in iOS development. In chapter 1,

you’ll get to develop your first Hello World app, but we’ll also cover some of the core

areas and concepts of iOS development. Chapter 2 covers the development environ-

ment, including Xcode for editing the code and user interface along with other con-

cepts and tools.

Chapter 3 begins part 2 with your first real app project: PicDecor. In this chapter

you’ll learn about view controllers and displaying images as well as how to interface

with sending email. You’ll see how to design the

, and how to connect it to the code

you’re writing.

Chapter 4 builds on what you learned in chapter 3 about view controllers by show-

ing you table view controllers and how to access the address book.

Chapter 5 continues with access to images through the photo album and the cam-

era and how to manipulate those images. Also, in chapter 5 you’ll see how to display a

map and the user’s location and store data for later retrieval and display.

The Settings Bundle is the official way to have a user manage app settings and is

covered in chapter 6. Also covered are playing MP3s and detecting motion (particu-

larly shaking) of the device. Chapter 7 goes further in playing audio, allowing the user

to make playlists and play them via the iPad framework. This includes covering Core-

Data for database design and for storing app data.

Push notifications and in-app purchase both use external server interaction for

their functionality and are covered in chapter 8 for our Rock, Paper, Scissors game.

Chapter 9 continues the game with GameCenter interaction including leaderboards

and achievements.

Chapter 10 could be called the “iChapter” as it covers using the iTunes

API

search music, designing for the iPad, and advertising using iAds.

Finally, chapter 11 covers the more recent additions to iOS. Specifically, it covers

the collection view, Social Framework, reminders, and

state restoration.

Code conventions

There are many Objective-C code examples in this book edited with Xcode. Source

code in listings and text is in a

fixed-width

font

this

to separate it from ordi-

nary text.

Writing code for a book is challenging compared with writing code that isn’t going

to be published for the world to see. Restrictions on line length, readability, and con-

ciseness encouraged decisions I might not have made otherwise. You will find that I

may have added a method to a class that might not make the most sense, or named

some variables in less-than-perfect ways. Please concentrate on the content over form

in those cases.

As all aspects of mobile, websites, documentation, tools, and so on change regu-

larly, some images in the book may not match what you see online and elsewhere.

However, the concepts are likely to remain, and the variance you might see shouldn’t

cause confusion.

Source code downloads

You will need a few things to benefit from the information presented in this book,

starting with an Apple computer. Then you will need to download Xcode and the

accompanying documentation, including public/open source libraries, as well as the

source code for the examples in the book. The chapters will then direct you on what

to do, one step at a time.

You will find the source code for the working examples in this book available for

download from the publisher’s website at www.manning.com/iOSinPractice.

You can also find some of the apps developed in this book in the Apple App Store.

About the title

The title of this book communicates its two core aspects—it covers i

development

both in general and in practice. Learning happens best through examples and exer-

cises‚ as opposed to learning about theories or concepts in isolation. So I’ve included

numerous hands-on techniques and examples to get you started in i

development.

About the author

Bear Cahill has worked in i

development at Brainwash Inc. since 2008 and through

the development of several dozen apps. Prior to that, Bear worked at

IBM

, Ericsson,

and Travelocity, among other companies.

From

REXX

BASIC

C++

to Java to Objective-C, along with several other lan-

guages, Bear has worked on a variety of platforms and technologies. He now focuses on

independent work, using friends to handle related server, Android, and other work.

Bear enjoys spending time with his wife and two sons around downtown Denton,

Texas. He has too many hobbies past and future to list here, so we’ll just say he’s never

been sky diving, scuba diving, or stage diving. No diving allowed!
