title: How to save MKMapRect in a plist
body: <p>I am creating a MKMapView application and in need to save a couple MKMapRect type variables in a plist so as to refer them when need.</p>
  
  <p>I know that MKMapRect has <code>MKMapPoint origin</code> and <code>MKMapSize size</code>. And they each have 2 double values that can be saved as <code>nsnumber</code> but saving all of them seems to be a lot of work and top of that i have to read the values back and convert them into a MKMapRect variable.</p>
  
  <p>So my question is that, is there any easy way to store a MKMapRect and retrive it back from a plist.</p>
  
  <p>Thanks,<br>
  Robin.</p>
