Question

I have these coordinate :

(45.463688, 9.18814) 
(46.0438317, 9.75936230000002)

and I need (trought Google API V3, I think) to get the dista

Answer 1

Try this

 CLLocationCoordinate2D coord1;
 coord1.latitude = 45.463688;
 coord1.longitude = 9.18814;
 CLLocation *loc1  = [[[CLLocation alloc] initWithLatitude:coord1.latitude longitude:coord1.longitude] autorelease];

 CLLocationCoordinate2D coord2;
 coord2.latitude = 46.0438317;
 coord2.longitude = 9.75936230000002;
 CLLocation *loc2  = [[[CLLocation alloc] initWithLatitude:46.0438317 longitude:9.75936230000002] autorelease];

 CLLocationDistance d1 = [loc1 distanceFromLocation:loc2];
