title: Can the memory used by MKMapView be released some how?
body: <p>I am using an <code>MKMapView</code> in my iPhone application. When I load this view, the <strong>activity monitor</strong> instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the <code>mapView</code> does not get freed up. Is there something that can be done to get all this memory back? </p>
