如何在 iPhone 版 gmap 中使用经纬度计算两地之间的距离？ 在 iPhone 版 gmap 中使用经纬度计算两个地点之间的距离

你必须使用核心定位框架。因此，不要忘记添加并导入核心位置框架。

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 CoreLocation

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

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

let distance = locA.distance(from: locB)
