Check before calling webservice internet is On or Off

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.

try the following code:

if (![self connected]) {

   // Alert message print. // Please check internet connection.
 } else {
  // Do call web server.
}

I did a test on iOS 8, the above code works on device. But on simulator, it is always returns true no matter wifi is on or off. After changing the reachability to:

Reachability *reachability = [Reachability reachabilityWithHostName:@"www.google.com"];

it worked on simulator.

The original code works on simulator with iOS 7. So possibly a bug for iOS 8.

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.

If you use AFNetworking library then it internaly check network connection and gives proper network error alerts. REF: http://afnetworking.com
