如何计算两点经纬之间的距离？ [英] How do I calculate the distance between two points of latitude and longitude?

问题描述

解决方案

我有一个特定地方的纬度和经度，我想计算距离$ p> CLLocation * location1 = [[CLLocation alloc] initWithLatitude：lat1 longitude：long1];
CLLocation * location2 = [[CLLocation alloc] initWithLatitude：lat2 longitude：long2];
NSLog（@Distance i meters：％f，[location1 distanceFromLocation：location2]）;
[location1 release];
[location2 release];


您还需要添加 CoreLocation.framework 到你的项目，并添加import语句：

  #import< CoreLocation / CoreLocation.h> 
  

i have latitude and longitude of particular place and i want to calculate the distance so how can i calculate it?

解决方案

CLLocation *location1 = [[CLLocation alloc] initWithLatitude:lat1 longitude:long1];
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:lat2 longitude:long2];
NSLog(@"Distance i meters: %f", [location1 distanceFromLocation:location2]);
[location1 release];
[location2 release];

You also need to add CoreLocation.framework to your project, and add the import statement:

#import <CoreLocation/CoreLocation.h>
