You can use FBNetworkReachabilty class to get network reachability on iOS device.

FBNetworkReachabilityConnectionMode mode =
[FBNetworkReachability sharedInstance].connectionMode;
switch (mode) {
case FBNetworkReachableNon:
break;
case FBNetworkReachableWiFi:
break;
case FBNetworkReachableWWAN:
break;
}
You can get the connection mode from 'connectionMode' property.

name:FBNetworkReachabilityDidChangeNotification
object:nil];
[[FBNetworkReachability sharedInstance] startNotifier];
- (void)didChangeNetworkReachability:(NSNotification*)notification
{
FBNetworkReachabiity* network = [notification object];
