title: Using Swift, is possible with UIAlertController prompt user to open location settings?
body: <p>In my Swift app, I check if <em>locationServiceEnabled()</em>. If it returns false, I should prompt user, with UIAlertController, to location settings.
  Is possible doing this?
  I use this func to prompt to location settings of the app:</p>
  
  <pre><code> func displayAlertToEnableLocationServicesApp()
  {
      let alertController = UIAlertController(
          title: "Location Access is Turned Off",
          message: "In order to locate your position, please open settings and set location access to 'While Using the App'",
          preferredStyle: .Alert)
  
      let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
      alertController.addAction(cancelAction)
  
      let openAction = UIAlertAction(title: "Settings", style: .Default) { (action) in
          if let url = NSURL(string: UIApplicationOpenSettingsURLString) {
              UIApplication.sharedApplication().openURL(url)
          }
      }
      alertController.addAction(openAction)
      self.presentViewController(alertController, animated: true, completion: nil)
  }
  </code></pre>
  
  <p>But this func open settings app, and not location setting.
  I need to open (settings -> privacy -> location)</p>
  
  <p>Thanks</p>
