title: How to ask permission from user for second time to allow to access the current location?
body: <p>In my app, if the user not allowed to access their current location, I can recieve that message in the following method</p>
  
  <pre><code>- (void)locationManager:(CLLocationManager*)aManager didFailWithError:(NSError*)anError
  {
      switch([anError code])
      {
         case kCLErrorLocationUnknown: 
          break;
  
          case kCLErrorDenied:
          {
             UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Access Denied" message:@"You didn't allow to access your current location" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
              [alert show];
            break;
          }
      }
   }
  </code></pre>
  
  <p>How to ask the user permission for the second time?</p>
  
  <p>I searched and got the answer NO, If the user wants the app to access his/her location, how he/she set the app to use their current location?</p>
  
  <p>Is deleting the app and download another one the only solution?</p>
