Introduction

How to Use This Book

This book is based on the class we teach at Big Nerd Ranch. As such, it was designed to be consumed

in a certain manner.

Set yourself a reasonable goal, like “I will do one chapter every day.” When you sit down to attack

a chapter, find a quiet place where you will not be interrupted for at least an hour. Shut down your

email, your Twitter client, and your chat program. This is not a time for multi-tasking; you will need to

concentrate.

Do the actual programming. You can read through a chapter first, if you like. But the real learning

comes when you sit down and code as you go. You will not really understand the idea until you have

written a program that uses it and, perhaps more importantly, debugged that program.

A couple of the exercises require supporting files. For example, in the first chapter you will need an

icon for your Quiz application, and we have one for you. You can download the resources and solutions

to the exercises from http://www.bignerdranch.com/solutions/iOSProgramming4ed.zip.

There are two types of learning. When you learn about the Peloponnesian War, you are simply adding

details to a scaffolding of ideas that you already understand. This is what we will call “Easy Learning.”

Yes, learning about the Peloponnesian War can take a long time, but you are seldom flummoxed by

it. Learning iOS programming, on the other hand, is “Hard Learning,” and you may find yourself

quite baffled at times, especially in the first few days. In writing this book, we have tried to create an

experience that will ease you over the bumps in the learning curve. Here are two things you can do to

make the journey easier:

• Find someone who already knows how to write iOS applications and will answer your questions.

In particular, getting your application onto the device the first time is usually very frustrating if

you are doing it without the help of an experienced developer.

• Get enough sleep. Sleepy people do not remember what they have learned.

How This Book is Organized

In this book, each chapter addresses one or more ideas of iOS development through discussion and

hands-on practice. For more coding practice, most chapters include challenge exercises. We encourage

you to take on at least some of these. They are excellent for firming up the concepts introduced in the

chapter and making you a more confident iOS programmer. Finally, most chapters conclude with one

or two “For the More Curious” sections that explain certain consequences of the concepts that were

introduced earlier.

Chapter 1 introduces you to iOS programming as you build and deploy a tiny application. You will get

your feet wet with Xcode and the iOS simulator along with all the steps for creating projects and files.

The chapter includes a discussion of Model-View-Controller and how it relates to iOS development.

Chapters 2 and 3 provide an overview of Objective-C and memory management. Although you will not

create an iOS application in these two chapters, you will build and debug a tool called RandomItems to

ground you in these concepts.

In Chapters 4 and 5, you will begin focusing on the iOS user interface as you learn about views and the

view hierarchy and create an application called Hypnosister.

Chapters 6 and 7 introduce view controllers for managing user interfaces with the HypnoNerd

application. You will get practice working with views and view controllers as well as navigating

between screens using a tab bar. You will also get plenty of experience with the important design

pattern of delegation as well as working with protocols, the debugger, and setting up local notifications.

Chapter 8 introduces the largest application in the book – Homepwner. (By the way, “Homepwner”

is not a typo; you can find the definition of “pwn” at www.urbandictionary.com.) This application

keeps a record of your possessions in case of fire or other catastrophe. Homepwner will take fourteen

chapters to complete.

In Chapters 8, 9, and 19, you will build experience with tables. You will learn about table views, their

view controllers, and their data sources. You will learn how to display data in a table, how to allow the

user to edit the table, and how to improve the interface.

Chapter 10 builds on the navigation experience gained in Chapter 6. You will learn how to use

UINavigationController and you will give Homepwner a drill-down interface and a navigation bar.

In Chapter 11, you will learn how to take pictures with the camera and how to display and store images

in Homepwner. You will use NSDictionary and UIImagePickerController.

In Chapters 12 and 13, you will set Homepwner aside for a bit to create a drawing application named

TouchTracker to learn about touch events. You will see how to add multi-touch capability and how to

use UIGestureRecognizer to respond to particular gestures. You will also get experience with the first

responder and responder chain concepts and more practice with NSDictionary.

In Chapter 14, you will learn how to use debug gauges, Instruments, and the static analyzer to optimize

the performance of TouchTracker.

In Chapters 15 and 16, you will make Homepwner a universal application – an application that runs

natively on both the iPhone and the iPad. You will also work with Auto Layout to build an interface

that will appear correctly on any screen size.

In Chapter 17, you will learn about handling rotation and using UIPopoverController for the iPad and

modal view controllers.

Chapter 18 delves into ways to save and load data. In particular, you will archive data in the

Homepwner application.

In Chapter 20, you will update Homepwner to use Dynamic Type to support different font sizes that a

user may prefer.

Chapter 21 takes another break from Homepwner and introduces web services as you create

the Nerdfeed application. This application fetches and parses an RSS feed from a server using

NSURLConnection and NSXMLParser. Nerdfeed will also display a web page in a UIWebView.

In Chapter 22, you will learn about UISplitViewController and add a split view user interface to

Nerdfeed to take advantage of the iPad’s larger screen size.

Chapter 23 returns to the Homepwner application with an introduction to Core Data. You will change

Homepwner to store and load its data using an NSManagedObjectContext.

In Chapter 24, you will add state restoration to Homepwner to let users return to the application right

where they left off – no matter how long they are away.

Chapter 25 introduces the concepts and techniques of internationalization and localization. You will

learn about NSLocale, strings tables, and NSBundle as you localize parts of Homepwner.

In Chapter 26, you will use NSUserDefaults to save user preferences in a persistent manner. This

chapter will complete the Homepwner application.

Introduction

Chapter 27 introduces the Core Animation framework with a brief return to the HypnoNerd application

to implement animations.

Chapter 28 introduces building applications using storyboards. You will piece together an application

using UIStoryboard and learn more about the pros and cons of using storyboards.

Style Choices

This book contains a lot of code. We have attempted to make that code and the designs behind it

exemplary. We have done our best to follow the idioms of the community, but at times we have

wandered from what you might see in Apple’s sample code or code you might find in other books. You

may not understand these points now, but it is best that we spell them out before you commit to reading

this book:

• We typically create view controllers programmatically. Some programmers will instantiate view

controllers inside XIB files or in a storyboard. We will discuss storyboards and demonstrate their

use a little, but, in reality, we seldom use them in our projects at Big Nerd Ranch.

• We will nearly always start a project with the simplest template project: the empty application.

When your app works, you will know it is because of your efforts – not because that behavior was

built into the template.

Typographical Conventions

To make this book easier to read, certain items appear in certain fonts. Class names, method names,

and function names appear in a bold, fixed-width font. Class names start with capital letters and

method names start with lowercase letters. In this book, method and function names are formatted the

same for simplicity’s sake. For example, “In the loadView method of the BNRRexViewController class,

use the NSLog function to print the value to the console.”

Variables, constants, and types appear in a fixed-width font but are not bold. So you will see, “The

variable fido will be of type float. Initialize it to M_PI.”

Applications and menu choices appear in the Mac system font. For example, “Open Xcode and select

New Project... from the File menu.”

All code blocks are in a fixed-width font. Code that you need to type in is always bold. For example, in

the following code, you would type in everything but the first and last lines. (Those lines are already in

the code and appear here to let you know where to add the new stuff.)

@interface BNRQuizViewController ()

@property (nonatomic, weak) IBOutlet UILabel *questionLabel;

@property (nonatomic, weak) IBOutlet UILabel *answerLabel;

@end

Necessary Hardware and Software

You can only develop iOS apps on an Intel Mac. You will need to download Apple’s iOS SDK,

which includes Xcode (Apple’s Integrated Development Environment), the iOS simulator, and other

development tools.
