title: IOS notification of wifi connection including SSID
body: <p>Newbie IOS programmer looking for a way to get notified when the IPhone connects to a WIFI network.</p>
  
  <p>i.e.
  Notification for the following transitions:
  3G to WIFI 
  WIFI to 3G
  WIFI to another WIFI</p>
  
  <p>It should be able to tell which SSID I am connected to ...</p>
  
  <p>This took about 20 minutes to figure out on Android, can't find a starting point for this function on IOS</p>
  
  <p>thanks</p>
