title: UIAlertView like "Turn On Location Services to allow maps to determine your location". Settings + Cancel
body: <p>I Want to emit this alert:</p>
  
  <pre><code>Turn On Location Services to allow maps to determine your location
  </code></pre>
  
  <p>I need both "Settings" and "Cancel" exactly like the "maps" application.</p>
  
  <p>"Settings" should open settings->general->location services</p>
  
  <p>I didn't find the way to open the settings page.</p>
  
  <p>Can you help me?</p>
  
  <p>Thanks</p>
