distanceFromLocation - Calculate distance between two points

Question

Just a quick question on Core Location, I\'m trying to calculate the distance between two points, code is below:

    -(void)locationChange:(CLLocation *)newL         


        

Answer 1

In Swift

Let's create a method function that calculates distance between two locations:

 func distanceBetweenTwoLocations(source:CLLocation,destination:CLLocation) -> Double{

        var distanceMeters = source.distanceFromLocation(destination)
        var distanceKM = distanceMeters / 1000
        let roundedTwoDigit = distanceKM.roundedTwoDigit
        return roundedTwoDigit

    }

If you want only two digits:

extension Double{

    var roundedTwoDigit:Double{

        return Double(round(100*self)/100)

        }
    }
