This document is about the first component of the development environment—the programming language and its runtime environment. It fully describes the Objective-C language, and provides a foundation for learning about the second component, the Mac OS X Objective-C application frameworks—collectively known as Cocoa. You can start to learnmore about Cocoa by reading Getting Started with Cocoa. The twomain development tools you use are Xcode and Interface Builder, described in Xcode User Guide and Interface Builder respectively. The Objective-C language is a simple computer language designed to enable sophisticated object-oriented programming. Objective-C is defined as a small but powerful set of extensions to the standard ANSI C language. Its additions to C are mostly based on Smalltalk, one of the first object-oriented programming languages. Objective-C is designed to give C full object-oriented programming capabilities, and to do so in a simple and straightforward way. For those who have never used object-oriented programming to create applications before, this document is also designed to help you become familiar with object-oriented development. It spells out some of the implications of object-oriented design and gives you a flavor of what writing an object-oriented program is really like

THE C PROGRAMMING LANGUAGE WAS pioneered by Dennis Ritchie at AT&T Bell Laboratories in the early 1970s. It was not until the late 1970s, however, that this pro- gramming language began to gain widespread popularity and support.This was because until that time C compilers were not readily available for commercial use outside of Bell Laboratories. Initially, C’s growth in popularity was also spurred on in part by the equal, if not faster, growth in popularity of the Unix operating system.This operating system, which was also developed at Bell Laboratories, had C as its “standard” programming lan- guage. In fact, well over 90% of the operating system itself was written in the C lan- guage! The enormous success of the IBM PC and its look-alikes soon made MS-DOS the most popular environment for the C language.As C grew in popularity across different operating systems, more and more vendors hopped on the bandwagon and started mar- keting their own C compilers. For the most part, their version of the C language was based on an appendix found in the first C programming text—The C Programming Language—by Brian Kernighan and Dennis Ritchie. Unfortunately, this appendix did not provide a complete and unambiguous definition of C, meaning that vendors were left to interpret some aspects of the language on their own. In the early 1980s, a need was seen to standardize the definition of the C language. The American National Standards Institute (ANSI) is the organization that handles such things, so in 1983 an ANSI C committee (called X3J11) was formed to standardize C. In 1989, the committee’s work was ratified, and in 1990, the first official ANSI standard def- inition of C was published. Because C is used around the world, the International Standard Organization (ISO) soon got involved.They adopted the standard, where it was called ISO/IEC 9899:1990. Since that time, additional changes have been made to the C language.The most recent standard was adopted in 1999. It is known as ANSI C99, or ISO/IEC 9899:1999. It is this version of the language upon which this book is based. C is a “higher-level language,” yet it provides capabilities that enable the user to “get in close” with the hardware and deal with the computer on a much lower level.This is 01 0672326663 CH01 6/10/04 2:04 PM Page 12 Chapter 1 Introduction because, although C is a general-purpose structured programming language, it was origi- nally designed with systems programming applications in mind and, as such, provides the user with an enormous amount of power and flexibility. This book proposes to teach you how to program in C. It assumes no previous expo- sure to the language and was designed to appeal to novice and experienced programmers alike. If you have previous programming experience, you will find that C has a unique way of doing things that probably differs from other languages you have used. Every feature of the C language is treated in this text.As each new feature is present- ed, a small complete program example is usually provided to illustrate the feature.This reflects the overriding philosophy that has been used in writing this book: to teach by example. Just as a picture is worth a thousand words, so is a properly chosen program example. If you have access to a computer facility that supports the C programming lan- guage, you are strongly encouraged to download and run each program presented in this book and to compare the results obtained on your system to those shown in the text. By doing so, not only will you learn the language and its syntax, but you will also become familiar with the process of typing in, compiling, and running C programs. You will find that program readability has been stressed throughout the book.This is because I strongly believe that programs should be written so that they can be easily read—either by the author or by somebody else.Through experience and common sense, you will find that such programs are almost always easier to write, debug, and modify. Furthermore, developing programs that are readable is a natural result of a true adherence to a structured programming discipline. Because this book was written as a tutorial, the material covered in each chapter is based on previously presented material.Therefore, maximum benefit will be derived from this book by reading each chapter in succession, and you are highly discouraged from “skipping around.”You should also work through the exercises that are presented at the end of each chapter before proceeding on to the next chapter. Chapter 2,“Some Fundamentals,” which covers some fundamental terminology about higher-level programming languages and the process of compiling programs, has been included to ensure that you understand the language used throughout the remainder of the text. From Chapter 3,“Compiling and Running Your First Program,” on, you will be slowly introduced to the C language. By the time Chapter 16,“Input and Output Operations in C,” rolls around, all the essential features of the language will have been covered. Chapter 16 goes into more depth about I/O operations in C. Chapter 17, “Miscellaneous and Advanced Features,” includes those features of the language that are of a more advanced or esoteric nature. Chapter 18,“Debugging Programs,” shows how you can use the C preprocessor to help debug your programs. It also introduces you to interactive debugging.The popular debugger gdb was chosen to illustrate this debugging technique. Over the last decade, the programming world has been abuzz with the notion of object-oriented programming, or OOP for short. C is not an OOP language; however, several other programming languages that are based on C are OOP languages. Chapter 19,“Object-Oriented Programming,” gives a brief introduction to OOP and some of its 01 0672326663 CH01 6/10/04 2:04 PM Page 23 Introduction terminology. It also gives a brief overview of three OOP languages that are based on C, namely C++, C#, and Objective-C. Appendix A,“C Language Summary,” provides a complete summary of the language and is provided for reference purposes. Appendix B,“The Standard C Library,” provides a summary of many of the standard library routines that you will find on all systems that support C. Appendix C,“Compiling Programs with gcc,” summarizes many of the commonly used options when compiling programs with GNU’s C compiler gcc. In Appendix D,“Common Programming Mistakes,” you’ll find a list of common pro- gramming mistakes. Finally,Appendix E,“Resources,” provides a list of resources you can turn to for more information about the C language and to further your studies. Answers to the quizzes at the end of chapters can be found at www.kochan-wood.com. This book makes no assumptions about a particular computer system or operating system on which the C language is implemented.The text makes brief mention of how to compile and execute programs using the popular GNU C compiler gcc. I want to thank the following people for their help in the preparation of various ver- sions of this text: Douglas McCormick, Jim Scharf, Henry Tabickman, Dick Fritz, Steve Levy,Tony Ianinno, and Ken Brown. I also want to thank Henry Mullish of New York University for teaching me so much about writing and for getting me started in the publishing business. An earlier edition of this book was also dedicated to the memory of Maureen Connelly, a former production editor at Hayden Book Company, the publishers of the first edition of this book

Object-oriented programming, like most interesting new developments, builds on some old ideas, extends them, and puts them together in novel ways. The result is many-faceted and a clear step forward for the art of programming. An object-oriented approach makes programs more intuitive to design, faster to develop, more amenable to modifications, and easier to understand. It leads not only to new ways of constructing programs, but also to new ways of conceiving the programming task. Nevertheless, object-oriented programming presents some formidable obstacles to those who would like to understand what it’s all about or begin trying it out. It introduces a new way of doing things that may seem strange at first, and it comes with an extensive terminology that can take some getting used to. The terminology will help in the end, but it’s not always easy to learn. Moreover, there are as yet few full-fledged object-oriented development environments available to try out. It can be difficult to get started. That’s where this book comes in. It’s designed to help you become familiar with object-oriented programming and get over the hurdle its terminology presents. It spells out some of the implications of object-oriented design and tries to give you a flavor of what writing an object-oriented program is really like. It fully documents the Objective-C language, an object-oriented programming language based on standard C, and introduces the most extensive object- oriented development environment currently available—OPENSTEP.

w Hello elcome to Learn Objective- C on the Mac! This book is designed to teach you the basics of the Objective- C language. Objective- C is a superset of C and is the language used by many (if not most) applications that have a true Mac OS X look and feel. This book teaches you the Objective- C language and introduces you to its companion, Apple’s Cocoa toolkit. Cocoa is written in Objective- C and contains all the elements of the Mac OS X user interface, plus a whole lot more. Once you learn Objective- C in this book, you’ll be ready to dive into Cocoa with a full- blown project or another book such as Learn Cocoa on the Mac or Begin- ning iPhone Development, both by Dave Mark and Jeff LaMarche (Apress 2009). In this chapter, we’ll let you know the basic information you need before you get started with this book. We’ll also serve up a bit of history about Objective- C and give you a thumbnail sketch of what’s to come in future chapters.

Certain technologies bring out everyone's hidden geek, and the iPhone did so instantly upon its release. Thousands of programmers want to provide applications on the iPhone, and this book shows you how to achieve the spectacular effects that made the device an immediate hit. You'll learn how to use an open, community-developed toolkit that has been widely downloaded and used. Author Jonathan Zdziarski, the developer of the first fully functional application using the open iPhone toolkit, now explains in clear language how to create applications using Objective-C and the iPhone API, which in some ways resembles Apple's desktop API and in some ways strikes new ground. iPhone Open Application Development covers:

The Objective-C Pocket Reference is a quick guide to the Objective-C programming language and some of its fundamental support libraries. This reference takes the form of brief explanations interspersed with examples and definitions. If you are experienced with Objective-C, this handbook will supply the definitions and examples you most often need to jog your memory. If you are coming to Objective-C from C++ or Java and prefer to jump right in and write code, this book will give you enough explanation to use the language's features appropriately.

这个可是稀缺好资源哦 iPhone in Action is an introductory book, intended to teach the basics of iPhone pro- gramming in a tutorial form. It covers the fundamentals of both major styles of pro- gramming for the platform: web development and SDK programming. You can read this book in one of three ways. We encourage you to read it straight through, from chapter 1 to 20. This will intro- duce the platform, introduce both major ways to program for the iPhone, offer advice on when one style of programming is more appropriate than the other, and step you through both styles in turn. If you prefer to read only about web development, you can just read parts 1 and 2. Note that we’ve included an introduction to Objective-C at the end of part 2 that will get you started on iPhone SDK programming, even if you’ve never used a compiled programming language before, so we encourage you to keep on going, and see what else you can learn. If you prefer to read only about SDK programming, you can just read parts 1, 3, and 4. We still encourage you to at least skim the chapters in part 2, because they include advice especially for SDK programmers, showing how lessons learned from the web can apply to the SDK as well.

The amazing success of iPhone and iPod touch is a clear indication that application developers are entering a brave new world of sophisticated, multifunctional mobile applications. No longer do applications and various media need to live in separate silos. Instead, applications on these Apple devices can bring together elements of Web 2.0 apps, traditional desktop apps, multimedia video and audio, and the cell phone. Professional iPhone ™ and iPod touch ® Programming: Building Applications for Mobile Safari ™ covers the various aspects of developing Web - based applications for the iPhone and iPod touch environments. Specifically, you will discover how to create a mobile application from the ground up, utilize existing open source libraries in your code, emulate the look and feel of built - in Apple applications, capture finger - touch interactions, using AJAX to load external pages, and optimize applications for Wi - Fi and the EDGE network.

Chapter 1. Introduction The "C" programming language was pioneered by Dennis Ritchie at AT&T Bell Laboratories in the early 1970s. It was not until the late 1970s, however, that this programming language began to gain widespread popularity and support. This was because until that time C compilers were not readily available for commercial use outside of Bell Laboratories. Initially, C's growth in popularity was also spurred on in part by the equal, if not faster, growth in popularity of the Unix operating system, which was written almost entirely in C. The Objective-C language was designed by Brad J. Cox in the early 1980s. The language was based on a language called SmallTalk-80. Objective-C was layered on top of the C language, meaning extensions were added to C to create a new programming language that enabled objects to be created and manipulated. NeXT Software licensed the Objective-C language in 1988 and developed its libraries and a development environment called NEXTSTEP. In 1992, Objective-C support was added to the Free Software Foundation's GNU development environment. This software is in the public domain, which means anyone who wants to learn how to program in Objective-C can do so by downloading its tools at no charge. In 1994 NeXT Computer and Sun Microsystems released a standardized specification of the NEXTSTEP system called OPENSTEP. The Free Software Foundation's implementation of OPENSTEP is called GNUStep. There's also a Linux version that includes the Linux kernel and the GNUStep development environment called, appropriately enough, LinuxSTEP. On December 20, 1996, Apple Computer announced that it was acquiring NeXT Software and the NEXTSTEP/OPENSTEP environment became the basis for the next major release of Apple's operating system, OS X. Apple's version of this development environment was called Cocoa. With built-in support for the Objective-C language, coupled with development tools such as Project Builder (or its successor Xcode) and Interface Builder, a powerful development environment was created for application development on Mac OS X. When contemplating writing a tutorial on Objective-C, a fundamental decision had to be made. As with all prior texts on Objective-C, I could write mine to assume the reader already knew how to write C programs. I could also teach the language from the perspective of using the rich library of routines, such as the Foundation and Application Kit frameworks. Some texts also take the approach of teaching how to use the development tools, like the Mac's Project Builder and Interface Builder. I had several problems adopting this approach. First, learning the entire C language before learning Objective-C is wrong. C is a procedural language containing many features that are not necessary for programming in Objective-C, especially at the novice level. In fact, resorting to some of these features goes against the grain of adhering to a good object-oriented programming methodology. It's also not a good idea to teach all the details of a procedural language before learning an object-oriented one. This starts the programmer off in the wrong direction, and gives the wrong orientation and mindset for fostering a good object-oriented programming style. Just because Objective-C is an extension to the C language doesn't mean you have to learn C first! So, I decided neither to teach C first nor to assume prior knowledge of the language. Instead, I decided to take the unconventional approach of teaching Objective-C and the underlying C language as a single integrated language, and from an object-oriented programming perspective. The purpose of this book is as its name implies: to teach you how to program in Objective-C. It makes few assumption about the platform you're running under, the development tools you have available, or the library of classes at your disposal. All that material can be learned elsewhere, after you've learned how to write programs in Objective-C. In fact, mastering that material will be much easier after you have a solid foundation on how to program in Objective-C. This book does not assume much, if any, previous programming experience. In fact, if you're a novice programmer, you should be able to learn Objective-C as your first programming language from this text. This book teaches Objective-C by example. As each new feature of the language is presented, a small complete program example is usually provided to illustrate the feature. Just as a picture is worth a thousand words, so is a properly chosen program example. If you have access to an Objective-C compiler, you are strongly encouraged to run each program (all of which are available online) and compare the results obtained on your system to those shown in the text. By doing so, not only will you learn the language and its syntax, but you will also become familiar with the process of compiling and running Objective-C programs.

Few platforms match the iPhone’s unique developer technologies. It combines OS X-based mobile computing with an innovative multitouch screen, location aware- ness, an onboard accelerometer, and more.When Apple introduced the iPhone Cocoa Touch SDK beta in early March 2008, developers responded in numbers that brought Apple’s servers to its knees.Apple delivered more than one hundred thousand SDK downloads in less than one week.The iPhone Developer’s Cookbook was written to address this demand, providing an accessible resource for those new to iPhone programming.

功能强大的javascript表格排序，可以设定排序规则，设定哪些列排序，哪些列不排序。运行速度快。两部操作就搞定，使用方便简单！解决服务器端数据库排序的压力！

ImageJ 支持图片格式转换，图片放大缩小等是一个不错的选择,压缩包中包括库文件,实例类,以及ImageJ的源代码!还有API帮助文档!DOC文档太大.暂不发送

当你有QQ消息时,QQ的小图标会晃动,我们甚至还可以设定QQ有消息时,自动弹出来! 这些在C/S模式下很容易实现!如果要在B/S模式如何来实现呢? 我们的肯定会想到在客服端调用ajax在后台不断的查询服务器.看是否有关于自己的消息.如果有则查询返回.这种做法肯定会大量的占用系统的资源!不可取! 现在DWR的反转AJAX功能.允许我们从服务器端来控制客服端.而不需要客户端来请求.服务器可以自动把消息发给指定的客户端! 我不能把公司的代码贴出来,所以我自己写了一个DEMO,已经实现了对指定用户发送消息的功能,并且即时显示在指定的用户界面上面.当然你可以修改这些,让它弹出来显示,或者像QQ一样在你页面的某个角落让消息的图标闪动:)
