MKMapView Zoom and Region

http://stackoverflow.com/questions/1166444/mkmapview-zoom-and-region

I can see in the MapKit framework is setRegion animated. As I understand I need to set a region's span's latitude and longitude delta values to specify zoom level. But I really don't have an idea what these values represent I read the documentation.. However span which is a MKCoordinateSpan consists of latitudeDelta the vertical distance represented by the region and longitudeDelta the horizontal distance represented by the region . A brief example. Here's a toy MKCoordinateRegion center latitude.. the horizontal distance represented by the region . A brief example. Here's a toy MKCoordinateRegion center latitude 0 longitude 0 span latitudeDelta 8 longitudeDelta 6 The region could be described using its min and max coordinates as follows min coordinate..
