立即下载 "Programming the iPhone User Experience" 是一本针对苹果iPhone和iPod Touch设备开发者的实用指南，它深入探讨了世界上最强大的移动操作系统——iOS平台的用户界面设计与编程技巧。这本书由Toby Boudreaux编写，旨在帮助开发者理解和掌握Cocoa Touch框架，这是构建iPhone和iPod Touch应用的核心工具。
书中内容涵盖了以下几个关键知识点：
1. **Cocoa Touch框架基础**：读者将学习如何运用Cocoa Touch框架来构建应用程序，这些框架为开发者提供了开发iOS应用所需的必要工具和库。
2. **用户界面理论与实践**：作者分享了理论和最佳实践，从用户界面设计的角度指导开发者如何开发出符合Apple Human Interface Guidelines (HIG)的应用程序，注重用户体验和易用性。
3. **Objective-C语言**：作为Cocoa Touch的主要编程语言，本书会详细介绍Objective-C，包括其语法、类和对象模型，以便开发者能够有效地编写定制化的代码。
4. **UIKit视图定制**：根据Apple的设计原则，读者可以学习如何按照HIG规范定制标准的UIKit视图，以创建出独特且符合iOS设计美学的交互体验。
5. **手势识别与多点触控**：书中详细介绍了如何使应用程序对用户的滑动、捏合、旋转等多点触控操作做出响应，以提升用户在实际设备上的互动性。
6. **用户体验扩展**：除了界面本身，作者还讨论了如何处理与网络和地理位置相关的用户体验问题，确保应用程序具备实时性和位置感知功能。
这本书不仅适合CTO、开发者，也适合UI/UX设计师阅读，它作为Apple HIG的补充资料，提供了实用的开发技巧，帮助开发者创造出创新、有趣且市场潜力巨大的iPhone和iPod Touch应用。此外，配套网站还会提供示例代码和用户界面，便于读者在实践中进一步学习和应用所学知识。
The second Cocoa Touch framework is the Foundation framework. You can think of
Foundation as the layer that abstracts many of the underlying operating system elements
such as primitive types, bundle management, file operations, and networking from the
user interface objects in UIKit. In other words, Foundation is the gateway to everything
not explicitly part of the user interface. As you’ll see in this book, user experience
programming goes deeper than the user interface controls and includes things such as
latency management, error handling, data caching, and data persistence.
UIKit Overview
The user interface comprises the elements of a device or application that users see, click,
and—in the case of Cocoa Touch—tilt, shake, or tap. User interfaces are a big part of
user experience. They provide the face of your product, and often a bit more.
For the most part, UIKit is just a limited subset of the AppKit framework for Mac OS
X. If you have experience developing Cocoa apps for the Mac, you will get your head
around UIKit fairly quickly. The main differences are that UIKit is tuned for specific
hardware interfaces and that it provides less functionality than AppKit. The reduced
scope of UIKit is primarily due to the differences in robustness between typical com-
puters and the iPhone or iPod Touch. Despite the omission of a few familiar elements,
UIKit is a very capable toolset.
The best way to understand the breadth of UIKit is with a visual topology of the frame-
work. Figures 1-1 and 1-2 show the layout of UIKit.
The core class from which all Cocoa objects inherit basic behavior is NSObject. The
NS prefix has roots in the non-Apple origins of Cocoa at NeXT. The early versions of
what is now Cocoa were called NextStep. Most Cocoa classes in Cocoa are subclasses
of NSObject, and many classes assume that NSObject is the foundation of objects being
passed around. For example, the class NSArray, which represents a collection of point-
ers, requires that any pointer it stores points to an NSObject subclass. In most cases,
any custom class you create should inherit from NSObject.
The names of classes in Cocoa are often very descriptive. The following illustrations
give an overview of the classes in UIKit. The purpose is to provide a view of the entire
collection of classes so that developers of all experience levels can see the breadth of
the frameworks.
In UIKit, all classes that respond to user input inherit from UIResponder, which is an
NSObject subclass that provides functionality around handling user input. Figure 1-1
focuses on the subclasses of UIResponder.
