title: How do you open iOS settings screen such as location?
body: <p>In my app I have location features but if location is turned off I'd like to prompt the user to turn location ON and give them a button tap to take them to the exact location in iOS.  The same applies to Settings/Privacy/Calendar.</p>
  
  <p>Can someone provide the know-how on navigating to iOS device settings screens?</p>
  
  <p>Thank you.</p>
