Is there an event for disconnecting from the internet on iOS?

Question

I have an application that requires an internet connection for a certain library I use (XIMSS for Communigate). It receives status updates from a server and I can't alter the source of the lib. Is there a way to detect that the device disconnected from the internet? I'd like to avoid having to ping a server every x seconds to see if there is still a connection.

Answer 1

Apple's Reachability does this for you. Notifies you as your connectivity changes.

Answer 2

In iOS you can check like that :-

-(BOOL)returnInternetConnectionStatus{

     ReachabilityLattest *reach = [ReachabilityLattest reachabilityForInternetConnection];
     NetworkStatus internetStatus = [reach currentReachabilityStatus];
     if ((internetStatus != NotReachable)) {
           return TRUE;
     } else {
           return FALSE;
     }
}
