Use cell connection if Wifi not available in iOS.

wifiReach = [ITMReachability reachabilityForLocalWiFi];
	[wifiReach startNotifier];
	
	NetworkStatus netStatus = [wifiReach currentReachabilityStatus];
    BOOL connectionRequired= [wifiReach connectionRequired];

switch (netStatus)
    {
        case NotReachable:
        {
            statusString = @"Access Not Available";
            connectionRequired= NO;
            break;
        }
            
        case ReachableViaWWAN:
        {
			NSLog(@"WWAN is reachable");
			wifiAvailable = YES;
            statusString = @"Reachable WWAN";
			UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Yes Reachable Login"
															message:@"Please enter the correct login details."
														   delegate:nil
												  cancelButtonTitle:@"OK"
												  otherButtonTitles:nil, nil];
			[alert show]
			;            break;
        }
        case ReachableViaWiFi:
        {
		
			wifiAvailable = YES;
			statusString= @"Reachable WiFi";
            break;
		}
    }

I have a login screen. On entering username and password app should check for WIFI/Cell and launch a web service. But on the device, when i turn off WiFi on purpose and try to use cell, it wont go ahead. I am stuck at login screen. How should i let my app work on cell(4g) as well.?If you need more info, please ask.Thanks

Your code only checks for wwan which is wifi you need to check for a host traceability instead on the other interface.

@KoolStar. How do i do that? Can you give me an example.

Why are you specifically checking reachability for wifi. Why not use reachabilityForInternetConnection or reachabilityWithHostName if you need to check a particular host address

edit: for example, instead of

wifiReach = [ITMReachability reachabilityForLocalWiFi];

try

wifiReach = [ITMReachability reachabilityForInternetConnection];

Now, obviously you would maybe want to change the name of that to something other than wifiReach, but you get the idea

@waterskier2007. Thanks. That solved my problem.
