MKMapView Zoom and Region

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

area around center . The center point should be obvious it's the center point of the region. However span which is a MKCoordinateSpan consists of latitudeDelta the vertical distance represented by the region and longitudeDelta the horizontal distance represented.. hand point latitude 4 longitude 3 So you can specify zoom levels around a center point by using an appropriately sized MKCoordinateSpan. As an approximation of Google's numeric zoom levels you could reverse engineer the span sizes that Google uses for a given..
