title: Zooming out with RMMapView constrained to coordinates
body: <p>I'm trying to setup an offline map in an iPhone app, but the result is not very good.</p>
  
  <p>I'm using the route-me framework, I've got an offline file .db (created by tiles2sqlite) and the map view is constrained with coordinates (using setConstraintsSW:NE:).</p>
  
  <p>My problem is appearing when zooming out (pinch gesture), this error message "Zooming will move map out of bounds: no zoom" is always present and it's very difficult to zoom out when you are not near the real center of the map.</p>
  
  <p>Is there a solution to have the same result as in Offmaps (iOS app) where the map has a nice scrollview behavior?</p>
  
  <p>Cheers.</p>
