/**
`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
Reachability can be used to determine background information about why a network operation failed, or to trigger a network operation retrying when a connection is established. It should not be used to prevent a user from initiating a network request, as it's possible that an initial request may be required to establish reachability.
See Apple's Reachability Sample Code ( https://developer.apple.com/library/ios/samplecode/reachability/ )
@warning Instances of `AFNetworkReachabilityManager` must be started with `-startMonitoring` before reachability status can be determined.
