iPhone Flashlight Programming Tutorial

Product Description
Here you will find interesting exercises that show you, step-by-step, how to write programs that use the iPhone’s built-in camera.

The book provides you with several unique benefits:

Unique Benefit #1: Written from scratch for the new iPhone OS 3.1 Camera Interface.

While other books cover the previous, less functional camera interface that was in iPhone OS 2.x and 3.0, this book focuses 100% on the new iPhone OS 3.1 Camera Interface.

Unique Benefit #2: Step-by-Step Exercises.

If you are a beginner, you can follow every step, and learn every key skill. If you are an expert, you can skip directly to those steps you need to refresh or enhanced your existing skills.

Unique Benefit #3: As few words as possible, but no fewer.

While some books focus on writing as many words as possible, the goal here is to write only the key words that you need to quickly learn and master iPhone programming skills.

The iPhone OS 3.1 technologies that you will use in these exercises include:

UIImagePickerController

This class handles the details of displaying a camera, a photo library, or a photo album. While this class existed in previous versions of iPhone OS, additional functionality was added in iPhone OS 3.1 to provide a camera overlay view and program control of taking a photo.

UIImagePickerControllerDelegate

This protocol provides two methods for notifying you of the user’s selection (cancel or select photo) when using the UIImagePickerController. As with the class, this protocol has additional functionality in iPhone OS 3.1.

UIImage

This class represents the image taken by the camera.

As you work through these exercises, here are some of the skills that you will learn.

* How to display the default camera.
* How to override the default camera with your own custom view.
* How to scale the camera image.
* How to save the camera image.
* How to take control of the camera shutter button, pressing the button under program control.

iPhone Camera Programming Exercises

Product Description
This book is about iPhone database programming. It provides a set of hands-on, step-by-step exercises.

The goal is to help you learn and master iPhone database programming quickly and easily.

Native iPhone OS database applications make use of the embedded SQLite database engine framework. Hence, learning iPhone database programming is learning how to use the embedded SQLite database engine.

The hands-on nature of these exercises is unique. True learning happens when you take action by performing hands-on exercises. That is what this book is about.

Here are the key iPhone Database Programming skills that you will learn:

- SQLite Framework (/usr/include/sqlite3.h, libsqlite3.dylib)
- SQLite Datatypes (NULL, INTEGER, REAL, TEXT, BLOB)
- SQLite Functions (sqlite3_open(), sqlite3_exec(), etc.)
- SQL Syntax (CREATE TABLE, INSERT INTO, etc.)
- Navigation-based Application (UITableViewController, UITableView, etc.)

Is this book for you? To find out, perform these two steps.

Step 1. Scan the Table of Contents, reading the title of each exercise. Each exercise focuses on a specific skill, and if the exercises look interesting to you, then this book is for you.

Step 2. Read through the first Exercise, and see if the clear, step-by-step instructions make sense to you. If so, then this book is for you.

If you have access to a Mac OS X system, along with the iPhone OS SDK (Software Developers Kit), then you can read each exercise, and perform each step, using the iPhone OS SDK.

However, even if you do not have a Mac OS X system with the iPhone OS SDK, you can still read and follow along “in your mind”. When you do have access to a Mac, you’ll know exactly what to do.

iPhone SDK Programming, A Beginner’s Guide

Product Description
This 2nd Edition of these popular iPhone Objective-C 2.0 exercises are for you if you are either a newbie or an expert iPhone Objective-C 2.0 software developer, and you need to learn, practice, and improve your iPhone Objective-C 2.0 software development skills.

The approach taken here is unique. Every exercise focuses on a key and important skill. Using a clear, step-by-step writing style, each exercise shows the exact code you need to enter. The exercises were written for use with Xcode, the Objective-C 2.0 development tool included with the iPhone OS SDK.

Unlike books that focus on Mac OS X Objective-C 2.0, the exercises in this book were written from scratch to focus on iPhone Objective-C 2.0 programming.

NOTE: The 1st Edition of these exercises did everything from the command-line. This 2nd Edition now does everything using the Xcode development tool that is included with the iPhone OS SDK.

The only prerequisite for these exercises is an eagerness to learn. While it helps to have a background in object-oriented programming, that is not a requirement. The exercises explain new concepts when they are needed, in a step-by-step, easy-to-understand, manner.

If you are an existing C/C++, C#, Flash, Java, PHP, Python, Ruby or similar developer, then you’ll enjoy how Objective-C 2.0 handles object-oriented programming. Objective-C was influenced by SmallTalk, one of the early object-oriented programming languages. In turn, Objective-C influenced the Java language designers, which in turn influenced the C# language designers.

iPhone OS uses Objective-C 2.0 as it’s programming language, which is a superset of the C programming language. As you work through these exercises, the Objective-C 2.0 concepts will be covered as you come to them. It’s OK if you do not have experience with Objective-C 2.0; just start Exercise 1 and work your way forward.

If you have access to a Mac OS X system, along with the iPhone OS SDK (Software Developers Kit), then you can read each exercise, and perform each step, using the iPhone OS SDK.

However, even if you do not have a Mac OS X system with the iPhone OS SDK, you can still read and follow along “in your mind”. When you do have access to a Mac, you’ll know exactly what to do.

iPhone Objective-C 2.0 Programming Exercises 2nd Edition

Product Description
What .NET C# developers need to enter the hot field of iPhone apps

iPhone applications offer a hot opportunity for developers. Until the open source MonoTouch project, this field was limited to those familiar with Apples programming languages. Now .NET and C# developers can join the party. Professional iPhone Programming with MonoTouch and .NET/C#is the first book to cover MonoTouch, preparing developers to take advantage of this lucrative opportunity. This book is for .NET developers that are interested in creating native iPhone applications written in .NET/C#. These developers want to use their existing knowledge. While .NET developers are always interested in learning, they also recognize that learning Objective-C and the specifics of the iPhone can be overwhelming. Those developers interested in MonoTouch will recognize that the cost of MonoTouch is easily made up by the ability to quickly target the iPhone using a language that they are already familiar with. This book is designed for .NET developers that want to target the iPhone. It is designed to help you get up to speed with the iPhone, not to really teach you about the .NET Framework or C# language, which we assume you already know. This book is designed with introductory material in Chapters 1 thru 4. You should read Chapters 1 thru 4 sequentially. These chapters introduce the MonoTouch product, the basics of developing with MonoTouch and MonoDevelop, and finally, the basics of presenting data to a user with screen and data controls and how to develop a user interface for the iPhone. Once you are comfortable with these concepts, you can typically move from one chapter to another and not necessarily have to read the chapters sequentially.

Chapter 1 “Introduction to iPhone Development with MonoTouch for C# Developers”This chapter looks at how the largest segment of developers can target the smartphone with the highest mindshare, and that the smartphone is growing faster in marketshare than any other device.

Chapter 2 “Introduction to MonoTouch”gives you a firm foundation in MonoTouch, MonoDevelop, Interface Builder, debugging, and deploying.

Chapter 3 “Planning Your App’s UI: Exploring the Screen Controls”teaches you about creating your application’s UI and specifically how the UI on the iPhone can differ from UIs that you might have created before. You also explore the Input & Value objects from the Interface Builder Objects Library.

Chapter 4 “Data Controls” shows the Interface Builder Objects Library Cocoa Touch classes for Controllers, Data Views, and Windows, Views, & Bars.

Chapter 5 “Working with Data on the iPhone”looks at the SQLite database engine as well as strategies to store data off the device on a central server through SOAP and REST (using XML and JSON) without tying up the user interface.

Chapter 6 “Displaying Data Using Tables”looks at displaying information in a table, using tables for navigation, taking advantage of UITableView’s built-in editing features, and adding a search bar to a table.

Chapter 7 “Mapping”covers CoreLocation and MapKit, using Location Services, and adding maps and geocoding to your application.

Chapter 8 “Application Settings”focuses on application settings, and looks at two aspects of settings for your MonoTouch app: the Info.plist and your settings bundle. It covers what settings you might want to set in your Info.plist and why, and then looks at what code it takes to read and use the settings that you save in the settings bundle. And it also takes you through the building of the settings that you might have in a social media-type application. Going through each step, you will examine the Root.plist inside the Property List Editor and see the settings dialog that will result from it.

Chapter 9 “Programming with Device Hardware” covers accelerometer device orientation, and proximity detection support, networking, and developing with battery life in mind.

Chapter 10 “Programming with Multimedia” discussing integrating images and the image picker, watching and recording videos, playing and recording audio, and using animation

Chapter 11 “Talking to Other Applications”discusses the ways you can use MonoTouch to talk to other applications on the iPhone, both Apple-built applications and those downloaded from the App Store. It also provides helpful ways of accessing the iPhone’s Address Book and the iPod music library.

Chapter 12 “Localizing for an International Audience” first defines internationalization and localization, then shows displaying translated text and images, formatting dates, times, and numbers, then extracting text for translation.

Chapter 13 “Programming the iPad” the capabilities of the iPad are, what new APIs and controls have been introduced that you can use in iPad-specific applications, and how to build applications that can work on both iPad and iPhone devices.

Chapter 14 “Just Enough Objective-C” provides you with a reference and introduction to Objective-C that will help you acquire an ability to comprehend Objective-C which is something that will come in very handy.

Chapter 15 “The App Store: Submitting and Marketing Your App”discusses all things App Store. First, it talks about the process that you need to go through before you are ready to submit – this includes final testing with Ad-Hoc builds and a presubmission checklist. Next it addresses actually submitting to the App Store, and then finally what to do with your app after it’s in the App Store. This chapter also touches on alternative monetization strategies such as ads or in app purchases.
