"Cocoa.and.Objective-C：Up.and.Running(2010.3)".Scott.Stevenson.文字版.pdf 《Cocoa and Objective-C：Up and Running》是由Scott Stevenson编著的一本关于Cocoa和Objective-C编程的书籍，特别针对iPad和iPhone应用开发。这本书是2010年的第三版，由O'Reilly Media, Inc.出版。在iOS应用开发中，Cocoa是Apple为Mac OS X操作系统提供的主要应用程序开发框架，而Objective-C则是一种面向对象的编程语言，是开发Apple平台应用的基础。本书旨在帮助开发者快速掌握这两项核心技术，从而能够构建功能丰富的iOS和Mac应用。书中可能涵盖了以下几个重要的知识点： 1. **Objective-C基础**：Objective-C语言的语法，包括消息传递机制、类、对象、协议、分类以及内存管理（例如ARC，Automatic Reference Counting）。 2. **Cocoa框架**：介绍了Cocoa的主要组件，如Foundation框架和AppKit（或UIKit），包括NSObjects、NSArrays、NSDictionaries等基本数据结构，以及事件处理、视图层次结构和用户界面设计。 3. **Model-View-Controller (MVC)**：Cocoa中的核心设计模式，用于组织应用的结构和逻辑，强调代码与界面的分离。 4. **Interface Builder**：Apple的可视化工具，用于构建和设计用户界面，与Xcode集成，使得开发者可以通过拖拽方式创建UI元素。 5. **Delegates和Notifications**：Cocoa中的通信机制，用于对象间的通信和事件响应。 6. **Core Data**：Apple的数据持久化框架，用于存储和检索应用程序的数据模型。 7. **多线程编程**：在iOS和Mac应用中实现并发和后台操作的技术，包括NSOperation和GCD（Grand Central Dispatch）。 8. **测试和调试**：如何使用Xcode的内置工具进行单元测试和应用调试。 9. **App Store提交流程**：发布应用到App Store的步骤，包括证书配置、版本控制和审核过程。 10. **最佳实践和设计原则**：如何编写高效、可维护的代码，遵循Apple的编程指导原则。通过阅读这本书，开发者可以深入理解Cocoa和Objective-C的核心概念，并具备实际开发iOS和Mac应用的能力。书中的实例和练习将有助于巩固理论知识并提高实战技能。

Now that you’ve read through the book, you’re ready to write some apps. This

short chapter gives you a few last pointers to help you on your way.

Using Code Examples

This book is here to help you get your job done. In general, you may use the code in

this book in your programs and documentation. You do not need to contact us for

permission unless you’re reproducing a significant portion of the code. For example,

writing a program that uses several chunks of code from this book does not require

permission. Selling or distributing a CD-ROM of examples from O’Reilly books does

require permission. Answering a question by citing this book and quoting example

code does not require permission. Incorporating a significant amount of example code

from this book into your product’s documentation does require permission.

Acknowledgments

My education didn’t follow the normal path. I taught myself how to program and

learned how to run a business mostly by trial and error. In the end, I think this is the

only option that would have worked for me, but it was possible only because of my

extremely patient and understanding family: my mom, Peggy; my dad, Alan; and my

sister, Jamie. You would not be reading this now if it was not for their support.

There are so many people that have helped me in my work life, but there are a few that

have had a direct impact on this book.

Michael Lopp and Angela Muller were ongoing sources of encouragement and inspi-

ration. This book first came into being over lunch when Michael mentioned something

along the lines of “everyone wants an animal on the cover of their book,” referring to

the iconic O’Reilly covers. By incredible coincidence, Brian from O’Reilly emailed me

about two weeks later. Had Michael not made that comment, this might not have

happened.

I had world-class tech reviewers for this project: Joar Wingfors, Michael Jurewitz, Rob

Rhyne, and Tim Triemstra. Joar, who I originally met through the tutorials I posted

online, tirelessly reviewed an ever-changing book, provided a wealth of essential com-

ments and suggestions, and even helped me fix some bugs in the code. He’s one of the

most talented engineers I know, and I am thrilled to have been able to get his help on

this.

Though he wasn’t involved in this project, I owe a lot to John Mora. He has an ability

to look an impossibly large task in the face and just do it, despite the usual doubts about

whether you know enough or have enough time. It is one of the most impressive traits

I know of, and John has it in spades. Thankfully, I think some of that rubbed off on

me over the 15 years I’ve known him.

Thanks to Kip Krueger for patiently helping me figure out the low-level details of mem-

ory and offering pointers when I was learning C. His mentoring is the reason I’m able

to teach these topics to you now.

When I first started learning Cocoa, there were only two books out on the topic. I chose

Aaron Hillegass’s book Cocoa Programming for Mac OS X ( A d d i s o n - W e s l e y ) . N o t o n l y

was it the first Mac programming book I read, it was the first technical book I actually

enjoyed. His book proved to me that you could write in a direct and personal style and

still be taken seriously. Having spent time with him in person, I can also add that he’s

a great guy. There’s no doubt that his influence is weaved into the tutorials I’ve written.
