Best option is to use Reachability.

You can put a checkmark when you are loading some data from the web(or anywhere) each and everytime.

    -(void)checkInternetConnection
{
    Reachability *r = [Reachability reachabilityWithHostName:@"www.google.com"];
    internetStatus = [r currentReachabilityStatus];
    if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN))
    {
        UIAlertView *myAlert = [[UIAlertView alloc]initWithTitle:@"No Internet Connection"   message:@"You require an internet connection via WiFi or cellular network."delegate:self cancelButtonTitle:@"Ok"otherButtonTitles:nil];
        [myAlert show];
        [myAlert release];
        return;
    } 
}

You can simply call this method everytime.

Hope it helps!!

May want to look at if(navigator.onLine) { onlineCode() } , HTML5 feature and iPhone supports HTML5.

also look into this on SO

Apple has a commonly used sample for this, Reachability isn't that bad to use, and will show you the path to go down.
