¿Cómo se mide la distancia en metros entre dos CLLocations?

Question

¿Cómo puedo obtener la distancia en metros entre dos CLLocation s? CLLocation no proporciona ningún método para hacerlo, seeems.

Answer 1

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

Answer 2

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];

Answer 3

+ (CLLocationDistance)distanceBetweenCoordinate:(CLLocationCoordinate2D)originCoordinate andCoordinate:(CLLocationCoordinate2D)destinationCoordinate {  
    CLLocation *originLocation = [[CLLocation alloc] initWithLatitude:originCoordinate.latitude longitude:originCoordinate.longitude]; 
    CLLocation *destinationLocation = [[CLLocation alloc] initWithLatitude:destinationCoordinate.latitude longitude:destinationCoordinate.longitude]; 
    CLLocationDistance distance = [originLocation distanceFromLocation:destinationLocation]; 
    [originLocation release]; 
    [destinationLocation release]; 

    return distance; 
} 

Answer 4

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]; 

Answer 5

Swift 3,0

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

let distance = location1.distance(from: location2) 

distance es en metros como Double
