我有特定地点的经度和纬度，我想计算距离，所以我怎么计算呢？

最佳答案

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];

您还需要将CoreLocation.framework添加到您的项目中，并添加import语句：

#import <CoreLocation/CoreLocation.h>
