And use this method in your helper class to create a user friendly network status string using Reachability class instance:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
- (NSString *)networkStatusString { NetworkStatus networkStatus = [AppDel.reachability currentReachabilityStatus]; /*NotReachable = 0, ReachableViaWiFi = 2, ReachableViaWWAN = 1*/ switch (networkStatus) { case NotReachable: _networkStatusString = @"Нет соединения."; break; case ReachableViaWiFi: { _networkStatusString = @"Wi-Fi"; break; } case ReachableViaWWAN: { _networkStatusString = @"WWAN"; break; } default: break; } return _networkStatusString; } |
