But I really don't have an idea what these values represent I read the.. 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 by the region.. 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..
