Reachability
Reachability 是一个 Objective-C 网络连接库，旨在监控 Apple 平台应用内的互联网访问和接口可用性。它作为一个内存管理的包装器，用于跟踪网络可达性，确保与自动引用计数兼容。
该库利用 Grand Central Dispatch 来监控网络接口变化并触发异步通知。它采用基于块的调度，在检测到网络可达性状态变化时立即执行自定义闭包。
该项目涵盖网络连接监控，允许应用跟踪设备何时获得或失去互联网访问。它包括处理离线状态以及配置哪些特定网络连接类型被视为可达的功能。
Features
- Network Connectivity Monitoring - Provides a library for tracking the real-time online or offline status of a client device.
- Offline State Management - Detects the lack of network connection to disable features or display offline warnings to the user.
- Network Interface Management - Handles different types of network connections on Apple platforms to ensure data is sent over the correct interface.
- Objective-C Libraries - Implements a network connectivity library specifically designed for the Objective-C programming language.
- Connectivity Notifications - Provides a mechanism to respond to network state changes using system notifications or execution blocks.
- Network Interface Reachability - Tracks network interface availability to determine the internet connectivity status of the device.
- Grand Central Dispatch - Utilizes Grand Central Dispatch to receive real-time network reachability updates without blocking the main thread.
- Interface Type Filtering - Filters network events by comparing active hardware interfaces against a predefined list of required connection types.
- System Socket Polling - Monitors low-level socket reachability by registering callbacks with the operating system network stack.
- Asynchronous Callback Dispatchers - Provides block-based dispatch to execute custom closures immediately upon detecting network state changes.
- GCD-Based Monitors - Uses Grand Central Dispatch system calls to detect network state changes and trigger asynchronous callbacks.
- Interface Reachability Configurations - Allows the application to define which network connection types are treated as reachable based on data requirements.
- Networking Libraries - Utility for monitoring network connectivity status.
