I want to make it so that it will show the amount of distance between two CLLocation coordinates. Is there someway to do this without a complex math formula? If there isn't how would you do it with a formula?
Glenn Howes
CLLocation has a distanceFromLocation method so given two CLLocations:
CLLocationDistance distanceInMeters = [location1 distanceFromLocation:location2];
or in Swift 4:
//: Playground - noun: a place where people can play
import CoreLocation
let coordinate₀ = CLLocation(latitude: 5.0, longitude: 5.0)
let coordinate₁ = CLLocation(latitude: 5.0, longitude: 3.0)
let distanceInMeters = coordinate₀.distance(from: coordinate₁) // result is in meters
you get here distance in meter so 1 miles = 1609 meter
if(distanceInMeters <= 1609)
{
// under 1 mile
}
else
{
// out of 1 mile
}

Swift 4.1
import CoreLocation
//My location
let myLocation = CLLocation(latitude: 59.244696, longitude: 17.813868)
//My buddy's location
let myBuddysLocation = CLLocation(latitude: 59.326354, longitude: 18.072310)
//Measuring my distance to my buddy's (in km)
let distance = myLocation.distance(from: myBuddysLocation) / 1000
//Display the result in km
print(String(format: "The distance to my buddy is %.01fkm", distance))
Try this out:
distanceInMeters = fromLocation.distanceFromLocation(toLocation)
distanceInMiles = distanceInMeters/1609.344
From Apple Documentation:
Return Value: The distance (in meters) between the two locations.

For objective-c
You can use distanceFromLocation
to find the distance between two coordinates.
Code Snippets:
CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:lat1 longitude:lng1];
CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:lat2 longitude:lng2];
CLLocationDistance distance = [loc1 distanceFromLocation:loc2];
Your output will come in meters.
func calculateDistanceInMiles(){
let coordinate₀ = CLLocation(latitude:34.54545, longitude:56.64646)
let coordinate₁ = CLLocation(latitude: 28.4646, longitude:76.65464)
let distanceInMeters = coordinate₀.distance(from: coordinate₁)
if(distanceInMeters <= 1609)
{
let s = String(format: "%.2f", distanceInMeters)
self.fantasyDistanceLabel.text = s + " Miles"
}
else
{
let s = String(format: "%.2f", distanceInMeters)
self.fantasyDistanceLabel.text = s + " Miles"
}
}
For swift 4
let locationOne = CLLocation(latitude: lat, longitude: long)
let locationTwo = CLLocation(latitude: lat,longitude: long)
let distance = locationOne.distance(from: locationTwo) * 0.000621371
distanceLabel.text = "\(Int(round(distance))) mi"
Swift 5.
func calculateDistance(mobileLocationX:Double,mobileLocationY:Double,DestinationX:Double,DestinationY:Double) -> Double {
let coordinate₀ = CLLocation(latitude: mobileLocationX, longitude: mobileLocationY)
let coordinate₁ = CLLocation(latitude: DestinationX, longitude: DestinationY)
let distanceInMeters = coordinate₀.distance(from: coordinate₁)
return distanceInMeters
}
use to
let distance = calculateDistance("add parameters")
