title: CLLocationManager zoom in-zoom out
body: <p>I have implemented a <code>CLLocationManager</code> to show user location. Once a user clicks a button, the map zooms in the user location. However, once the user would like to zoom out back, it does not allow user to zoom out. Actually, it zooms out a little bit, but again it zooms in!! </p>
