iPhone MapView gets removed
<p>I have a tabBar in my application. In one of the section i have two views which i toggle between using segment buttons.</p>

<p>In one of the view i have MapView which i use to display list of users using their pic as annotation. On the other view i have tableView which shows the same users in table format. </p>

<p>Now everything is working fine, i am getting all the users and it displays fine on the map. It works perfectly most of the time on all device and all iOS but sometimes when i bring the mapView to front or toggle or try to zoom in. Both the views (tableView and mapView) just gets removed somehow and i see black screen (which is btw my superview so thats not a problem). </p>

<p>Does anyone know why this happens. It happens frequently on iPhone 3G the older iPhone. </p>

<p>Thanx for any help.</p>
