How to detect loss of internet reachability when wifi source loses connection?

Question

I am trying hard to get the authentic internet connectivity status. I have used Apple\'s Reachability but it\'s only giving me the status of wifi connectivity i.e. not covering

Answer 1

I was getting too the Wifi flag even with it disconnected. There is a bug in the Reachability.m method:

- (NetworkStatus)networkStatusForFlags:(SCNetworkReachabilityFlags)flags

it uses a BOOL as return value, but it assigns to it the values of a struct with 3 values:

typedef enum : NSInteger {
    NotReachable = 0,
    ReachableViaWiFi,
    ReachableViaWWAN
} NetworkStatus;

So if whether Wifi or Cellular are available, it will ReachableViaWiFi (as a BOOL can be 0 or 1, but not two)

To fix it, just change in the method above this:

BOOL returnValue = NotReachable;

For this:

int returnValue = NotReachable;

And you're good to go. Hope it helps.
