Since then, he has written software using every language and hard- ware platform that he could get his hands on, including a brief and painful foray into Fortran on a VAX system during his engineering education. Patrick holds a BS degree in Civil Engineering from Rutgers University and an MS in Computer Science from Stevens Institute of Technology. Professionally, Patrick has focused on data-centric applications for clients ranging from small busi- ness databases to large-scale systems for the United States Air Force. Currently, he is focused on the promise of mobility and developing connected applications for mobile devices such as the iPhone and iPad. When he can back away from the computer, Patrick enjoys gaming (especially Starcraft), photog- raphy, traveling, and doing just about anything with his family. You can follow him on Twitter at pwalessi and read his blog at iphonedevsphere.blogspot.com. ABOUT THE TECHNICAL EDITOR MICHAEL GILBERT is a long-time systems programmer for various engineering rms.

Over the years, he has continued to develop gaming software on PC and Mac for clients worldwide. He’s also an expert Flash ActionScript programmer and has produced a popular Internet gaming environment called HigherGames. He now enjoys developing games for the iPhone and iPad, and currently has several games in the AppStore, with more on the way.

Mary James, my acquisitions editor, shepherded this second edition through the acquisitions process. My project editor, Brian MacDonald, was there to answer every question that I had about writing and the publishing process. Mike Gilbert, my technical editor, gave up valuable app development time to review my work. I would also like to thank all the other editorial and production staff that put many hours into this project to help get it to print. I cannot thank my wife, Cheryl, and my stepdaughter, Morgan, enough for putting up with my ts, general crankiness, and lack of time for fun family activities as I worked my way through writ- ing this book. Your patience with me is astounding. I want to thank my Mom for introducing me to computers at a very young age and teaching me the basics. Finally, I want to thank my Dad for pushing me to work hard and for showing me how to be a father. ffirs.indd viiffirs.indd vii 4/1/2013 9:22:43 AM4/1/2013 9:22:43 AM www.it-ebooks.info ffirs.indd viiiffirs.indd viii 4/1/2013 9:22:43 AM4/1/2013 9:22:43 AM www.it-ebooks.info [...]... valuable for many categories of application development outside of the business realm Anyone writing an application that deals with data in just about any way should fi nd this book useful This should not be your fi rst book on iOS application development You will not fi nd a "Hello World" iOS application here There are many good books on learning to build basic iOS applications I have aimed this book... view-based application using Xcode that displays your data using the UITableView control You will also gain an understanding of the Model-View-Controller (MVC) architecture that underlies most iOS applications www.it-ebooks.info c01.indd 3 4/1/2013 2:38:26 PM 4 ❘ CHAPTER 1 INTRODUCING DATA-DRIVEN APPLICATIONS BUILDING A SIMPLE DATA-DRIVEN APPLICATION Many applications that you will build for iOS will... 22 The SQLite Library SQLite and Core Data 22 23 Building a Simple Database 24 Designing the Database Creating the Database Populating the Database Tools to Visualize the SQLite Database Connecting to Your Database Starting the Project The Model Class The DBAccess Class Parameterized Queries Writing to the Database Displaying the Catalog Viewing Product Details 25 27 29 33 36 36 39 40 49 50 51 53 Moving... the backbone of most applications It is not limited only to business applications Games, graphics editors, and spreadsheets all use and manipulate data in one form or another One of the most exciting things about iOS applications is that they enable you and your customers to take your data anywhere The mobility of iOS devices gives the developer an amazing platform for developing applications that work... in detail Finally, all iOS applications have a user interface, and I cover building user interfaces using storyboards Even though my original goal was to write a book for enterprise developers, I believe I have written one that is useful when developing applications of just about any type WHAT’S NEW IN THIS EDITION Since the fi rst edition of this book, much has changed in the iOS development community... types of applications that you can create for iOS and Mac OS X, as shown in Figure 1-1 FIGURE 1-1: New Project dialog Each option presented provides you with the basic setup needed to start developing your application The default iOS templates are divided into three groups: Application, Framework & Library, and Other www.it-ebooks.info c01.indd 4 4/1/2013 2:38:27 PM Building a Simple Data-Driven Application. .. graphics-intensive applications You will not be using OpenGL in this book ➤ Page-Based Application: This template provides a starting point for a page-based application that uses a page view controller You can use this template to build applications that incorporate page layout and page turning animations like iBooks ➤ Single View Application: This template provides a starting point for an application that... or nib file that contains the view The calculator application is an example of a single view application ➤ Tabbed Application: This template provides a starting point for an application that uses a tab bar It provides a user interface configured with a tab bar controller, and view controllers for the tab bar items The Clock application is a tabbed application The tabs at the bottom let you switch between... display data on iOS is the UITableView As the name suggests, the UITableView is a view that you can use to display data in a table You can see the UITableView in action in iOS s Contacts application The application displays your list of contacts in a UITableView control You learn much more about the UITableView control in Chapter 3 Typically, when developing the interface for your iOS applications, you... iPad CHAPTER 1: Introducing Data-Driven Applications CHAPTER 2: The iOS Database: SQLite CHAPTER 3: Displaying Your Data: The UITableView CHAPTER 4: User Interface Elements www.it-ebooks.info c01.indd 1 4/1/2013 2:38:24 PM www.it-ebooks.info c01.indd 2 4/1/2013 2:38:26 PM 1 Introducing Data-Driven Applications WHAT’S IN THIS CHAPTER? ➤ Creating a view-based application using Xcode ➤ Building a simple .
