找到CLLocationCoordinate2D点之间的距离

问题描述

我从文档中了解到，我们可以使用函数 distanceFromLocation：找到两个 CLLocation 点之间的距离。但我的问题是我没有CLLocation数据类型与我，我有CLLocationCoordinate2D点。那么如何找到两个CLLocationCoordinate2D点之间的距离。我看过帖子但对我没有帮助。

解决方案

您应该使用

<$ p $创建一个CLLocation对象p> - （id）initWithLatitude：（CLLocationDegrees）latitude
经度：（CLLocationDegrees）经度;


然后，您应该可以使用

$ b来计算距离$ b

  [location1 distanceFromLocation：location2]; 
  

I know from documentation we can find distance between two CLLocation points using the function, distanceFromLocation:. But my problem is I dont have CLLocation data type with me, I have the CLLocationCoordinate2D points. So how can I find distance between two CLLocationCoordinate2D points. I have seen the post post but not helpful for me.

解决方案

You should create an object of CLLocation using,

- (id)initWithLatitude:(CLLocationDegrees)latitude
    longitude:(CLLocationDegrees)longitude;

Then, you should be able to calculate the distance using

[location1 distanceFromLocation:location2];
