I am using Reachability sample code from Apple site. I have added Reachability.h and Reachability.m files to my project, also I have added SystemConfiguration.framework. Added #import "Reachability.h" to my view controller .m file and declared reachability variable in my view controller .h file. Everything compiles without errors until I start using Reachability instances.Reachability.h enumerates three types: NotReachable, ReachableViaWiFi and ReachableViaWWAN.But i Want to check ReachableViaWiFiNetwork or Reachable ViaCarrierData Network.how it possible plz give any code snnipet or link. Thanlks in advance.
