Excerpts

From the moment it first published Mac OS X, Apple Computer has made a complete suite of application-development tools available to every Macintosh user. Since Mac OS X version 10.3, those tools have been led by Xcode, the development environment that Apple's engineers use to develop system software and such applications as Safari, iTunes, Mail, and iChat. These same tools are in your hands. A solid text editor with syntax coloring and API-based code completion The industry-standard gcccompiler suite A graphical, interactive debugger based on the GNU debugger (gdb) A mature human interface (UI) layout and object-linkage editor for Carbon and Cocoa Tools for gaining detailed insights into optimizing performance Audience I wrote this book for three types of readers. 1. Newcomers curious about the world of Mac OS X development 2. Experienced UNIX-family operating systems users who want an introduction to the Mac OS X tool set 3. Xcode users wanting to supplement their techniques Step into Xcodewill not attempt to teach programming, a programming language, or any of the Mac OS X programming frameworks; good books on those subjects have already been written. My aim is to focus squarely on using the Xcode tool set. Most of the book uses one example project--not as a showcase for the programming techniques involved but as a framework for how to do Mac development with these tools. The CD-ROM accompanying this book provides the complete project directory--bugs and all!--for each chapter. Many of the examples in this book follow the progress of an application project that begins with a UNIX command line tool and progresses to a Core Data-based application with Spotlight support. As you follow along, you won't have to peck out every file and setting yourself. The CD-ROM directory, Examples, includes a copy of the project at every major stage of development--at least one version for each chapter. You can simply copy the current example project to your hard drive; the only errors are the ones I made deliberately. Structure of the Book Step into Xcodeis divided into two parts. Part I introduces Xcode and Mac OS X development against the background of developing a simple application from a BSD command line tool to a Tiger-savvy Cocoa application taking advantage of Core Data and Spotlight. Chapter 1 introduces Xcode with the obligatory "Hello, World" demonstration. Chapter 2 demonstrates the typical Xcode workflow by building a command line tool that will form the heart of the application we'll be building throughout Part I. Chapter 3 moves from passive use of the Xcode debugger to active use, interrupting program flow to examine the workings of a flawed application. Chapter 4 shows what happens in compilation and linkage, both generally and in Mac OS X. Chapters 5, 6, and 7 wrap our command line tool in a Cocoa graphical interface. The Model-View-Controller design pattern is matched to the tools Xcode provides to implement it. Chapter 8 focuses on property lists, a must-know subject in Mac OS X development, and shows how to create text macros for Xcode. Chapter 9 moves our command line tool into a static library, showing how to build such a library and how to integrate a dependent target with Xcode's build system. Chapter 10 examines bundles and package directories. Most of the targets Xcode can produce are varieties of bundles. We look at the ubiquitous Info.plist file. Chapter 11 develops techniques for creating custom view classes for Cocoa and shows how the development tools support them. Chapter 12 extends the odyssey of our library from library to framework, showing how to package a dynamic library and its headers for sharing or for embedding in an application. Chapter 13 surveys the Xcode options
