具体描述

What .NET C# developers need to enter the hot field of iPhone apps iPhone applications offer a hot opportunity for developers. Until the open source MonoTouch project, this field was limited to those familiar with Apple’s programming languages. Now .NET and C# developers can join the party. Professional iPhone Programming with MonoTouch and .NET/C# is the first book to cover MonoTouch, preparing developers to take advantage of this lucrative opportunity. This book is for .NET developers that are interested in creating native iPhone applications written in .NET/C#. These developers want to use their existing knowledge. While .NET developers are always interested in learning, they also recognize that learning Objective-C and the specifics of the iPhone can be overwhelming. Those developers interested in MonoTouch will recognize that the cost of MonoTouch is easily made up by the ability to quickly target the iPhone using a language that they are already familiar with. This book is designed for .NET developers that want to target the iPhone. It is designed to help you get up to speed with the iPhone, not to really teach you about the .NET Framework or C# language, which we assume you already know. This book is designed with introductory material in Chapters 1 thru 4. You should read Chapters 1 thru 4 sequentially. These chapters introduce the MonoTouch product, the basics of developing with MonoTouch and MonoDevelop, and finally, the basics of presenting data to a user with screen and data controls and how to develop a user interface for the iPhone. Once you are comfortable with these concepts, you can typically move from one chapter to another and not necessarily have to read the chapters sequentially. Chapter 1 "Introduction to iPhone Development with MonoTouch for C# Developers" This chapter looks at how the largest segment of developers can target the smartphone with the highest mindshare, and that the smartphone is growing faster in marketshare than any other device. Chapter 2 "Introduction to MonoTouch" gives you a firm foundation in MonoTouch, MonoDevelop, Interface Builder, debugging, and deploying. Chapter 3 "Planning Your App's UI: Exploring the Screen Controls" teaches you about creating your application's UI and specifically how the UI on the iPhone can differ from UIs that you might have created before. You also explore the Input & Value objects from the Interface Builder Objects Library. Chapter4 "Data Controls" shows the Interface Builder Objects Library Cocoa Touch classes for Controllers, Data Views, and Windows, Views, & Bars. Chapter 5 "Working with Data on the iPhone" looks at the SQLite database engine as well as strategies to store data off the device on a central server through SOAP and REST (using XML and JSON) without tying up the user interface. Chapter 6 "Displaying Data Using Tables" looks at displaying information in a table, using tables for navigation, taking advantage of UITableView's built-in editing features, and adding a search bar to a table. Chapter 7 "Mapping" covers CoreLocation and MapKit, using Location Services, and adding maps and geocoding to your application. Chapter 8 "Application Settings" focuses on application settings, and looks at two aspects of settings for your MonoTouch app: the Info.plist and your settings bundle. It covers what settings you might want to set in your Info.plist and why, and then looks at what code it takes to read and use the settings that you save in the settings bundle. And it also takes you through the building of the settings that you might have in a social media-type application. Going through each step, you will examine the Root.plist inside the Property List Editor and see the settings dialog that will result from it. Chapter 9 "Programming with Device Hardware" covers accelerometer device orientation, and proximity detection support, networking, and developing with battery life in mind. Chapter 10 "Programming with Multimedia" discussing integrating images and the image picker, watching and recording videos, playing and recording audio, and using animation Chapter 11 "Talking to Other Applications" discusses the ways you can use MonoTouch to talk to other applications on the iPhone, both Apple-built applications and those downloaded from the App Store. It also provides helpful ways of accessing the iPhone's Address Book and the iPod music library. Chapter 12 "Localizing for an International Audience" first defines internationalization and localization, then shows displaying translated text and images, formatting dates, times, and numbers, then extracting text for translation. Chapter 13 "Programming the iPad " the capabilities of the iPad are, what new APIs and controls have been introduced that you can use in iPad-specific applications, and how to build applications that can work on both iPad and iPhone devices. Chapter 14 "Just Enough Objective-C" provides you with a reference and introduction to Objective-C that will help you acquire an ability to comprehend Objective-C which is something that will come in very handy. Chapter 15 "The App Store: Submitting and Marketing Your App" discusses all things App Store. First, it talks about the process that you need to go through before you are ready to submit - this includes final testing with Ad-Hoc builds and a presubmission checklist. Next it addresses actually submitting to the App Store, and then finally what to do with your app after it's in the App Store. This chapter also touches on alternative monetization strategies such as ads or in app purchases.

iPhone高级编程:使用Mono Touch和.NET/C#

用户评价

这本书的实战性远超我的预期，它不是那种只停留在理论概念的“纸上谈兵”。我最欣赏的是作者构建的那些复杂示例项目。它们不是那种为了演示某个小功能而拼凑起来的玩具代码，而是结构完整、具备生产环境潜力的应用骨架。拿关于集成第三方地图服务的章节来说，它不仅包含了基本的地图渲染，更细致地讲解了如何在MonoTouch中处理异步回调、如何管理生命周期事件，以及如何将地图视图与其他UI组件进行高效的响应式交互。这种对完整开发流程的把控，是新手教程常常缺失的。此外，作者对调试和性能优化的重视也值得称赞。他们分享了如何利用Xcode的Instruments工具配合Visual Studio进行高效的内存泄漏排查和CPU性能瓶颈定位，这些都是实战中耗费大量时间才能摸索出来的经验，被如此系统地整理出来，极大地缩短了我的试错周期。这本书真正做到了将框架的使用与平台级的最佳实践紧密结合，使读者能够构建出既跨平台又接近原生性能的应用。

初次捧读此书，我的期望值其实是偏低的，毕竟“MonoTouch”这个名字在近年的iOS开发讨论中已经不再是主流声音，市场的主流叙事早就转向了Swift和SwiftUI。然而，这本书的价值恰恰在于它的历史深度和对底层原理的扎实剖析。作者没有回避跨平台框架在性能和原生API访问上的挑战，反而将其视为深入理解iOS操作系统工作原理的绝佳切入点。例如，书中关于如何通过P/Invoke和C# P/Invoke访问Objective-C Runtime的章节，那段对Selector和Method Swizzling的解释，清晰得令人拍案叫绝。这不仅仅是教你如何“调用”API，更是教你理解API背后的“为什么”和“如何实现”。对于那些在做维护遗留项目或者需要进行高度定制化、深入系统底层交互的场景，这种知识的深度是无可替代的。我甚至因此反思了自己在原生Swift开发中那些“理所当然”的使用习惯，开始追溯其在底层是如何被桥接和映射的。这本书的叙事风格非常严谨，几乎没有一句废话，全是干货，读起来需要高度集中精力，但读完后的收获感是极强的，它提供了一种从C#视角审视移动开发的独特视角。

这本书的封面设计着实吸引人，那种深邃的蓝色调，配上简洁有力的字体，让人一眼就能感受到其专业性和技术深度。我是在寻找一本能将我已有的.NET/C#功底有效迁移到iOS原生开发领域的桥梁时，发现了它。坦白讲，市面上关于移动开发的入门书籍多如牛毛，但真正能深入讲解平台特有机制、同时又照顾到我们这些“旧世界”开发者心智模型的精品少之又少。我尤其欣赏作者在讲解MvvmLight Toolkit在跨平台移动应用架构中的应用时所展现出的细致入微。他们没有停留在简单的界面绑定层面，而是深入探讨了数据同步、依赖注入在大型项目中的最佳实践，这对于构建健壮、可维护的应用至关重要。阅读过程中，我惊喜地发现，很多在传统WinForms或WPF项目中困扰我的设计模式问题，在MonoTouch的语境下得到了全新的、更具移动设备特性的解答。对于那些渴望从企业级应用开发转型到移动生态，但又不想完全抛弃C#生态优势的资深程序员来说，这本书无异于一份精心绘制的航海图。它的详实程度，甚至让我感觉像是在跟随一位经验丰富的资深架构师进行为期数周的深度技术辅导，而不是简单地翻阅一本技术手册。

我必须承认，这本书的阅读体验在初期略有门槛，主要是因为它对开发者的前提知识要求较高，如果你对C#的内存管理、CLR的工作原理以及面向对象设计的深层概念不熟悉，可能会感到吃力。但如果你已经具备了扎实的后端开发背景，那么这本书的价值会随着阅读的深入而呈指数级增长。它不仅仅是关于MonoTouch的API手册，更是一本关于如何将企业级应用的设计哲学（如SOLID原则、领域驱动设计）成功移植到资源受限、事件驱动的移动平台上的深度研讨录。书中关于异步编程模型，特别是Task Parallel Library (TPL)在处理UI更新和网络请求时的优雅适配，给我留下了深刻印象。它展示了如何用C#的现代特性去驾驭移动开发的异步洪流，避免了传统回调地狱。这种对语言特性的深刻理解和应用，使得最终生成的代码库不仅功能强大，而且逻辑清晰、易于团队协作和长期维护，完全符合专业级软件工程的标准。

这本书的篇幅虽然厚重，但其内容组织却展现出极高的逻辑性。从基础环境搭建和“Hello World”的差异化处理开始，逐步过渡到对Core Animation的C#封装、对Core Data的异步操作优化，再到最终的应用发布流程，整个知识体系的构建是层层递进、水到渠成的。我特别喜欢其中关于自定义控件绘制的章节，作者没有使用任何“黑魔法”，而是详尽地解释了iOS图形渲染管线的概念，并指导我们如何使用C#代码去高效地操作底层图形上下文。这使得我不再惧怕那些复杂的、需要精确控制像素的UI需求。这本书没有对任何一个关键技术点浅尝辄止，它似乎假定读者有能力理解复杂的概念，并且鼓励我们去探索框架之外的更底层原理。总而言之，它更像是一本“内功心法”而非“招式秘籍”，教会你如何在这个特定的技术栈中建立起坚不可摧的工程内功。对于那些追求技术深度而非表面光鲜的资深开发者来说，这是一部值得反复研读的经典之作。
