Determining when an EDGE connection comes back after a dropout on an iPhone

Question

I\'ve incorporated Apple\'s Reachability sample into my own project so I know whether or not I have a network connection - if I don\'t have a network connection, I don\'t bother

Answer 1

There is a nice reachability example on the net. it works wonderfully well: http://servin.com/iphone/iPhone-Network-Status.html

But you see, when I try to use it my own way, it just bombs.

Tried to implement it using:

NSString *sCellNetwork;     
 NSString *sNetworkReachable;  

if (flags & kSCNetworkFlagsReachable || flags & kSCNetworkReachabilityFlagsIsWWAN)

{do it} 

 else {
   Network fail alert; 
}

Answer 2

Reachability notificataions didn't seem to be reliable for me either, for detecting Wi-Fi. So I just use polling instead. Checking every 5 seconds seems to do no harm.

- (void) checkReachability {
    BOOL connected = ([[Reachability sharedReachability] localWiFiConnectionStatus] == ReachableViaWiFiNetwork);

    // Do something...

    [self performSelector:@selector(checkReachability) withObject:nil afterDelay:5.0];
}
