Reachability not working as expected

Question

Downloaded Reachability from Apple, using this method to check for an active connection:

-(BOOL)isReachable{

    Reachability *r = [Reachability reachabilityWithHostName:@"http://www.google.com"];

    if(NotReachable == [r currentReachabilityStatus]) {
        NSLog(@"Not Reachable");
        return NO;
    }

    NSLog(@"Reachable");
    return YES;  

}

Returns NO every single time despite being connected? Can't figure out why...

Any ideas? Thanks.

On a side note, can anyone recommend a good clean Reachability singleton class?

Answer 1

EDITED: you should remove the protocol, http from your reachabilityWithHostName call, so updated it to

 Reachability *reachability = [Reachability reachabilityWithHostname:@"www.google.com"];
 NetworkStatus netStatus = [reachability currentReachabilityStatus];

Answer 2

Use this code to check whether the device is connected to internet or not

use this code in viewDidLoad :

 Reachability* internetReachable; = [Reachability reachabilityForInternetConnection];
    [internetReachable startNotifier];

    hostReachable = [Reachability reachabilityWithHostName: @"www.apple.com"] ;
    [hostReachable startNotifier];

and add this function to your code:

-(void) checkNetworkStatus:(NSNotification *)notice
{
    recheabilityBool=FALSE;
    nonrecheabilityBool=FALSE;
    // called after network status changes
    NetworkStatus internetStatus = [internetReachable currentReachabilityStatus];
    switch (internetStatus)
    {
        case NotReachable:
        {
            nonrecheabilityBool=TRUE;
            internetCon=0;
            //NSLog(@"The internet is down.");


            break;
        }
        case ReachableViaWiFi:
        {
            NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
            internetCon=404;
            [prefs setInteger:internetCon forKey:@"conKey"];

            //NSLog(@"The internet is working via WIFI.");
            break;

        }
        case ReachableViaWWAN:
        {
            //NSLog(@"The internet is working via WWAN.");

            break;
        }
    }

    NetworkStatus hostStatus = [hostReachable currentReachabilityStatus];
    switch (hostStatus)
    {
        case NotReachable:
        {
            internetCon=0;
            if( nonrecheabilityBool==FALSE)
            {
                //NSLog(@"A gateway to the host server is down.");
            }
            break;

        }
        case ReachableViaWiFi:
        {
            if(recheabilityBool==FALSE)
            {

                recheabilityBool=TRUE;

                NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
                internetCon=404;
                [prefs setInteger:internetCon forKey:@"conKey"];


                //NSLog(@"The internet is working via WIFI.");
                break;
            }


            //NSLog(@"A gateway to the host server is working via WIFI.");

            break;
        }
        case ReachableViaWWAN:
        {
            //NSLog(@"A gateway to the host server is working via WWAN.");
            break;
        }
    }
}


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

I have a same issue with the Tony Million's Reachability : network status was always set to NotReachable. I fix it with adding the SystemConfiguration Framework

Hope it helps
