ios - Find Network Connectivity using Reachability -

I have integrated the rechargeability v2.2 in my app. I just wanted to know that sometimes the iPhone is connected to wifi but the internet is not used. So how can I get this?

Please explain the answer to this question properly. I want to show on the label that there is no limited or no contact.

  rechargeability * accessibility = [relabelability accessibility name: @ "http: // google .com "]; NetworkStats position = [reachability current resheability credits];
