Check before calling webservice internet is On or Off

Question

Want to check is Internet is available or not-available before calling any WEB-SERVER.

I used the Reachiablity which provided by apple to check the internet is on or off. I added this two files into my project. Reachability.h and Reachability.m

In ViewController.h

 -(BOOL)connected;

and ViewController.m its Implementation.

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

before calling webserver making an condtion

if([self connection] == true){

// Do call web server.
}

else {
// Alert message print. // Please check internet connection.
}

When running the application in both case with WIFI ON or OFF with MACBOOKPRO "Simulator" or on Device. Its always returns true condition.

Please let me know, what should i need to do properly for making reachablity work.

I am using Xcode 6.0.1 IOS SDK 8.0.

@ALL Thank In Advance.

Why bother? If there's no network connection, you'll get a perfectly good error back from your attempt. Reachability is useful for knowing when a connection has returned, if you had network jobs queued up, but it's pointless to check before every web call.

You need error handling code anyway, because a missing connection is only one of several reasons a request could return an error. In this case reachability is adding extra code for no benefit, which is true of most uses I've seen.
