   1.난 그냥 코드 아래를 시도 할 필요는 server.If에서 잘못된 응답을 받았습니다 그래서 실제로 소스 및 대상 변수는 .. 전무했다

   func addRoutesOverLayForMapView(){
   
       var source:MKMapItem?
       var destination:MKMapItem?
       var sourcePlacemark = MKPlacemark(coordinate: pickUpDistanceLocation!.coordinate, addressDictionary: nil)
       source = MKMapItem(placemark: sourcePlacemark)
   
       var desitnationPlacemark = MKPlacemark(coordinate: dropOffDistanceLocation!.coordinate, addressDictionary: nil)
       destination = MKMapItem(placemark: desitnationPlacemark)
       let request:MKDirectionsRequest = MKDirectionsRequest()
       request.setSource(source)
       request.setDestination(destination)
       request.transportType = MKDirectionsTransportType.Walking
   
       let directions = MKDirections(request: request)
       directions.calculateDirectionsWithCompletionHandler ({
           (response: MKDirectionsResponse?, error: NSError?) in
   
           if error == nil {
   
               self.showRoute(response!)
           }
           else{
   
           println("trace the error \(error?.localizedDescription)")
   
           }
       })
    }
   
   func showRoute(response:MKDirectionsResponse){
       for route in response.routes as! [MKRoute]{
           mapView.addOverlay(route.polyline, level: MKOverlayLevel.AboveRoads)
           var routeSeconds = route.expectedTravelTime
           let routeDistance = route.distance
           println("distance between two points is \(routeSeconds) and \(routeDistance)")
   
   
       }
   
   }
   

   그리고이 대리자 메서드를 구현해야는지도보기 대리자를 설정하는 것을 잊지 해달라고

     func mapView(mapView: MKMapView!, rendererForOverlay overlay: MKOverlay!) -> MKOverlayRenderer! {
   
           if overlay is MKPolyline {
               var polylineRenderer = MKPolylineRenderer(overlay: overlay)
               polylineRenderer.lineDashPattern = [14,10,6,10,4,10]
               polylineRenderer.strokeColor = UIColor(red: 0.012, green: 0.012, blue: 0.012, alpha: 1.00)
               polylineRenderer.lineWidth = 2.5
               return polylineRenderer
           }
           return nil
   
       }
