title: iOS Send data via Internet when connection is enable
body: <p>I'm working on an app that should work without connection. The user can insert some data and when the app detects that Internet connection is enable, it have to send this data. </p>
  
  <p>Internet connection can be WIFI or carrier connection.</p>
  
  <p>How I can do that? I found something called "Reachability", but I'm not sure.</p>
  
  <p>The app must support iOS6 and iOS7</p>
