title: IOS check on app if GPS is off
body: <p>Hi I have an app that gives you locations on the mapview, is there any method to implement on an IF.</p>
  
  <p>I would like my app to check if you don't have the gps active instead of showing you the map it will show you an image saying you don't have connection.</p>
  
  <p>I would like to do something similar if you don't have signal as well.</p>
