I have this code but for some reason it's just drawing a rout between 2 points (first, and last points) ignoring all other points which is [index == 1 to index == n-1 ]
output : route between only 2 markers
expected output : route between all markers (5 markers)
Is any body knows what is the wrong with my code ?
func getDotsToDrawRoute(positions : [CLLocationCoordinate2D], completion: @escaping(_ path : GMSPath) -> Void) {
if positions.count > 1 {
let origin = positions.first
let destination = positions.last
var wayPoints = ""
for point in positions {
wayPoints = wayPoints.characters.count == 0 ? "\(point.latitude),\(point.longitude)" : "\(wayPoints)|\(point.latitude),\(point.longitude)"
}
print("this is fullPath :: \(wayPoints)")
let request = "https://maps.googleapis.com/maps/api/directions/json"
let parameters : [String : String] = ["origin" : "\(origin!.latitude),\(origin!.longitude)", "destination" : "\(destination!.latitude),\(destination!.longitude)", "wayPoints" : wayPoints, "stopover": "true", "key" : kyes.google_map]
Alamofire.request(request, method:.get, parameters : parameters).responseJSON(completionHandler: { response in
guard let dictionary = response.result.value as? [String : AnyObject]
else {
return
}
print ("route iss ::: \(dictionary["routes"])")
if let routes = dictionary["routes"] as? [[String : AnyObject]] {
if routes.count > 0 {
var first = routes.first
if let legs = first!["legs"] as? [[String : AnyObject]] {
let fullPath : GMSMutablePath = GMSMutablePath()
for leg in legs {
if let steps = leg["steps"] as? [[String : AnyObject]] {
for step in steps {
if let polyline = step["polyline"] as? [String : AnyObject] {
if let points = polyline["points"] as? String {
fullPath.appendPath(path: GMSMutablePath(fromEncodedPath: points))
}
}
}
let polyline = GMSPolyline.init(path: fullPath)
polyline.path = fullPath
polyline.strokeWidth = 4.0
polyline.map = self._map }
}
}
}
}
})
}
}
