Reachability
Reachability is an Objective-C network connectivity library designed to monitor internet access and interface availability within Apple platform applications. It serves as a memory-managed wrapper for tracking network reachability, ensuring compatibility with automatic reference counting.
The library utilizes Grand Central Dispatch to monitor network interface changes and trigger asynchronous notifications. It employs block-based dispatch to execute custom closures immediately upon detecting a change in the network reachability state.
The project covers network connectivity monitoring, allowing applications to track when a device gains or loses internet access. It includes capabilities for handling offline states and configuring which specific network connection types are treated as reachable.
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.
