以下为详尽部分，如感觉过于冗长，可移步《iOS 开发库概要（iOS Developer Library Summary）》。
iOS 开发库组织结构，按三种方式对共计 1687 份文档进行分类管理：
1、按资源类型（Resource Types）分类：所有文档都属于某个分类；
2、按主题（Topics）分类：大多数文档会属于某个主题；
3、按框架（Frameworks）所处操作系统层次结构分类：编程指南及参考手册大多会属于某个框架；
有三部分是最基础的：
1、语言与开发工具：

2、基于操作系统的语言特性：
基础框架（Foundation）：共206篇
使用基础框架作为 Objective-C 编程的基本要素。该框架提供了基本的 Objective-C 类，最重要的根类 NSObject 定义了对象的基本行为。它包含了用对象来表示基本数据类型、集合以及操作系统服务的类。基础框架也引入了许多设计模式和一些有助于 Objective-C 稳健、高效地编程的机制。基础框架（Foundation）和用户界面开发包（UIKit）一起，提供了实现图形化、事件驱动的 iOS 应用所需的基本工具和基础设施。
Use the Foundation framework for the "nuts and bolts" classes for Objective-C programming. This framework provides essential Objective-C classes, most importantly the root class, NSObject, which defines basic object behavior. It includes classes for objects representing basic data types, collections, and operating-system services. Foundation also introduces several design patterns and mechanisms that contribute to the robustness and efficiency of Objective-C programs. Along with UIKit, the Foundation framework provides the basic tools and infrastructure you need to implement graphical, event-driven iOS applications.
