推荐答案

你必须使用Core Location Framework.所以不要忘记添加 &导入核心位置框架.

You have to use Core Location Framework. So don't forget to Add & import Core Location Framework.

 #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];

import CoreLocation

let locA = CLLocation(latitude: lat1, longitude: long1)

let locB = CLLocation(latitude: lat2, longitude: long2)

let distance = locA.distance(from: locB)
