2つのCLLocation間の距離をメートル単位で測定するにはどうすればよいですか？

2つのCLLocations間の距離をメートル単位で取得するにはどうすればよいですか？ CLLocationはそれを行うための方法を提供していません、と思われます。

CLLocationDistance distance = [aCLLocationA distanceFromLocation:aCLLocationB];
// distance is a double representing the distance in meters

Jonas Schnelli
CLLocationDistance distance = [secondLocation distanceFromLocation:firstLocation];  //      distance is expressed in meters

CLLocationDistance kilometers = distance / 1000.0;
// or you can also use this..
CLLocationDistance meters = distance;

NSString *distanceString = [[NSString alloc] initWithFormat: @"%f", kilometers];

flot totaldistancecovered = [distanceString floatValue];

//Now,you can use this float value for addition...
// distanceMoved  should be float type variable which is declare in .h file...

 distanceMoved = distanceMoved + totaldistancecovered ;
 theLabel.text = [NSString stringWithFormat: @"%f meters", distanceMoved];

CLLocation *loc1 = [[CLLocation alloc]  initWithLatitude:dblLatitude longitude:dblLongitude];   
CLLocation *loc2 = [[CLLocation alloc]  initWithLatitude:dblCurrentLatitude longitude:dblCurrentLongitude];
double dMeters = [loc1 distanceFromLocation:loc2];
[loc1 release];
[loc2 release];

Swift 3.0

let location1 = CLLocation(latitude: <CLLocationDegrees>, longitude: <CLLocationDegrees>)
let location2 = CLLocation(latitude: <CLLocationDegrees>, longitude: <CLLocationDegrees>)

let distance = location1.distance(from: location2)

distanceはメートル単位でDouble
