Am trying to calculate distance from one point to another. I am able to find method for that.

CLLocationDistance dist = [loc distanceFromLocation:loc2];

But what it does is calculate distance in a straight line.

What I want is to calculate distance by roadways.

For Example: Lets say If i give from address as Home and To address as Work. I want the distance between Home to Work by roadways. By roadways I get 750meters. But if i calculate by the method distanceFromLocation I get only 400meters. Can someone help me with an example to calculate distance.

  • Thanks Ill check right now – Jaff May 31 '16 at 06:02
  • I think these are the things I want MKDirections and MKDirectionsRequest. I tried using the calculateDirectionWithCompletionHandler. My response getting error. – Jaff May 31 '16 at 06:54

Check out this answer : 

CLLocationCoordinate2D pointACoordinate = [pointAAnnotation coordinate];
CLLocation *pointALocation = [[CLLocation alloc] initWithLatitude:pointACoordinate.latitude longitude:pointACoordinate.longitude];  

CLLocationCoordinate2D pointBCoordinate = [pointBAnnotation coordinate];
CLLocation *pointBLocation = [[CLLocation alloc] initWithLatitude:pointBCoordinate.latitude longitude:pointBCoordinate.longitude];  

float distanceMeters = [pointALocation distanceFromLocation:pointBLocation];
float distanceMiles = (distanceMeters / 1609.344);

Here pointAAnnotation & pointBAnnotation are the two Annotations which you need to calculate distance between them.

  • Thanks for the reply. I want to calculate distance between two location by road ways. The distanceFromLocation: will draw a straight path between two locations and give that distance right? Lets say If i give from address as Home and to address as work. I want the distance between from Home to Work by roadways. By roadways I get 750meters. But if i calculate distanceFromLocation I get only 400meters. – Jaff May 31 '16 at 06:26
  • Yes.. this will return direct Straight line length. Better you try with google Api to get exact Distance – Balaji Ramakrishnan May 31 '16 at 06:58
