iPhone dev - showing two locations on the map
- by Brian
Now I have the coordinate of two locations, let say
locationA with latitude 40 and longitude -80,
locationB with latitude 30 and longitude -70,
I want to create a mapView that I can see both locations with appropriate viewing distance.
I got the new coordinate by finding the midpoint (in this example, {35, -75}),
but the question is,
How can I get an appropriate viewing distance?
In particular, how can I calculate CLLocationDistance (if I'm using MKCoordinateRegionMakeWithDistance) or MKCoordinateSpan (if I'm using MKCoordinateSpanMake).
Thanks in advance.
