How can I get the distance in meters between two CLLocation
s? CLLocation
doesn't provide any method to do it, it seeems.

回答1:
CLLocationDistance distance = [aCLLocationA distanceFromLocation:aCLLocationB];
// distance is a double representing the distance in meters
回答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];
Hope, this will help you...

+ (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;
}
回答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];

Swift 3.0
let location1 = CLLocation(latitude: <CLLocationDegrees>, longitude: <CLLocationDegrees>)
let location2 = CLLocation(latitude: <CLLocationDegrees>, longitude: <CLLocationDegrees>)
let distance = location1.distance(from: location2)
distance
is in meters as a Double
