Reachability class not working with 3g connection

-(BOOL)connected
{
    Reachability *reachability = [Reachability reachabilityForInternetConnection];
    NetworkStatus networkStatus = [reachability currentReachabilityStatus];
    return !(networkStatus == NotReachable);
}


if (![self connected]) {


    NSLog(@"Not Connected");
} else {        
    NSLog(@"Connected");

    // connected, do some internet stuff
}

The above code is perfectly working with Wifi.When i use 3G connectivity it is not working correctly.I do not know how to change code for 3G connectivity.any help will be appreciated.thanks in advance.

Solution

  • Reachability is only used to detect if a system has connection to a gateway to the internet but doesn't go in-depth and check whats behind it. There a times when a LAN is reachable but there no gateway to the internet. You're have to make a actual real request to a server. Take a look at this great sample code on how to implement on all types of connectivity
