CHTReachability

Your device may connect to a wireless AP via Wi-Fi but the AP's cable is unplugged, or it may connect to a base station but your service provider stop working for some reasons. What's the easiest way to know current network status? CHTReachability tries to detect REAL network reachability for you.

Features

Easy to use.
Highly customizable.

Prerequisite

ARC
iOS 8+

How it works

It uses Apple's Reachability and SimplePing sample codes to do the real works.

First it uses Reachability to check network reachability.
When network status is Reachable then it uses SimplePing to ping specified host.
The status changes from Reachable to Online if it receives packet.
