Pro Objective-C

Pro Objective-C The Objective-C programming language continues to grow in popularity and usage because of the power and ease-of-use of the language itself, along with the numerous features that continue to be added to the platform. If you have a basic knowledge of the language and want to further your expertise, Pro Objective-C is the book for you. Pro Objective-C provides an in-depth, comprehensive guide to the language, its runtime, and key API’s. It explains the key concepts of Objective-C in a clear, easy to understand manner, and also provides detailed coverage of its more complex features. In addition, the book includes numerous practical examples--code excerpts and complete applications--that demonstrate how to apply in code what you’re learning. The book begins with an exploration of Objective-C's basic features and key language elements. After reviewing the basics, it proceeds with an in-depth examination of the Objective-C dynamic programming features and runtime system. Next the book covers the Foundation Framework, the base layer of APIs that can be used for any Objective-C program. Finally, new and advanced features of Objective-C are introduced and shown how they make the Objective-C language even more powerful and expressive. Each topic is covered thoroughly and is packed with the details you need to develop Objective-C code effectively. The most important features are given in-depth treatment, and each chapter contains numerous examples that demonstrate both the power and the subtlety of Objective-C. Start reading Pro Objective-C and begin developing high-quality, professional apps on the OS X and iOS platforms using the Objective-C programming language! What you’ll learn Objective-C fundamentals and key language elements Objective-C runtime system Foundation Framework APIs Objective-C advanced language features Xcode Essentials Debugging with LLDB Who this book is forThis book is geared towards intermediate to advanced developers who already have some Objective-C experience and want pro-level coverage of the language, including advanced Objective-C features, recent additions to the language, and practical usage of its core frameworks and APIs. It's also great for those developers not familiar with Objective-C that have done some C programming and also understand object-oriented programming concepts. Objective-C作为编程语言，在移动和桌面应用开发领域一直保持着重要的地位。由于其本身的强大功能和易用性，以及不断添加的新特性，Objective-C的普及度和使用率持续增长。《Pro Objective-C》这本书是为了那些已经具备基础Objective-C知识，希望进一步提升自己专业水平的开发者们准备的。书籍内容包含以下几个方面： 1. Objective-C的基本特性以及关键语言元素。书籍一开始会对Objective-C的基础知识进行讲解，包括其基本语法和核心概念，为后面更深入的内容打下坚实的基础。 2. Objective-C的动态编程特性和运行时系统。动态编程是Objective-C的一个核心特性，它允许程序在运行时进行类型检查、内存管理等操作。这部分会深入探讨这些动态特性的工作机制以及如何在实际编程中使用。 3. Foundation框架。作为Objective-C语言的基底层API，Foundation框架提供了丰富的接口来简化开发工作。书中会介绍Foundation的通用类、系统服务以及专业服务，涵盖从基本数据结构到网络编程、文件操作等领域的广泛应用。 4. Objective-C的高级语言特性。本书还会介绍Objective-C的高级特性，比如预处理、自动引用计数（ARC）、运行时API使用等，让开发者能够编写出更加高效和安全的代码。 5. Xcode以及LLDB调试工具的使用。Xcode是苹果官方提供的集成开发环境，也是开发iOS和macOS应用的必备工具。了解如何使用Xcode中的编辑器、调试器和性能分析工具是高效开发的基础。而LLDB作为新一代的调试工具，能够提供强大的调试功能，本书会教授如何在Xcode环境下使用LLDB进行代码调试。 6.如何开始使用Objective-C。书中也包含了从零开始学习Objective-C的实践指南，这为没有Objective-C经验的开发者提供了一个入口。对于那些有C语言背景且理解面向对象编程概念的开发者来说，这将是一个很好的起点。 《Pro Objective-C》适合的读者群体是那些已经具备一定Objective-C基础，并希望提高到专业级别的人。它不仅仅覆盖了Objective-C的高级特性，还包括了语言的最新发展以及核心框架和API的实际使用方法。对于那些不熟悉Objective-C但已经做过一些C语言编程的开发者来说，也是极好的学习资源，因为Objective-C语言在很多方面继承了C语言的特点。通过阅读本书，读者将会学会： - Objective-C的基本概念和核心语言元素。 - Objective-C的运行时系统以及动态特性。 - Foundation框架的APIs。 - Objective-C的高级语言特性，如ARC、运行时API的使用等。 - Xcode环境下的核心开发工具使用。 -使用LLDB进行高效调试。整本书内容详尽，每个主题都有深入的探讨和丰富的实例，不仅解释了Objective-C的强大功能，也展示了其在编写高质量、专业级应用程序时的精妙之处。通过阅读《Pro Objective-C》，开发者可以将Objective-C语言应用于OS X和iOS平台，编写出优秀的应用程序。
