使用MKMapKit查找两点之间的距离 [英] Find distance between two points using MKMapKit

问题描述

我正在尝试使用iPhone OS 3.2在MKMapView上的两点之间找到以米为单位的欧几里得距离.问题是我在纬度和经度方面拥有这些坐标，这在数学上为我提供了足够的数据来查找距离，但是这将需要一些棘手的三角学.有没有更简单的解决方案?

I'm attempting to find the euclidean distance in meters between two points on an MKMapView using iPhone OS 3.2. The problem is that I have these coordinates in terms of latitude and longitude, which, mathematically provides me enough data to find the distance, but it's going to take some tricky trigonometry. Is there any simpler solution?

谢谢！

推荐答案

CLLocation具有一种为您计算距离的方法:

CLLocation has a method to calculate the distance for you:

- (CLLocationDistance)distanceFromLocation:(const CLLocation *)location
