Calculate distance between two place using latitude-longitude in gmap for iPhone [duplicate]
You have to use Core Location Framework. So don't forget to Add & import Core Location Framework.
Objective-C
#import <CoreLocation/CoreLocation.h> CLLocation *locA = [[CLLocation alloc] initWithLatitude:lat1 longitude:long1]; CLLocation *locB = [[CLLocation alloc] initWithLatitude:lat2 longitude:long2]; CLLocationDistance distance = [locA distanceFromLocation:locB]; //distance in Meters //1 meter == 100 centimeter //1 meter == 3.280 feet //1 square meter == 10.76 square feet [locA release]; [locB release];Swift
import CoreLocationlet locA = CLLocation(latitude: lat1, longitude: long1)let locB = CLLocation(latitude: lat2, longitude: long2)let distance = locA.distance(from: locB)
