道順アプリ曖昧なメンバー

Question

私は道順がapですが、「directionsusinggoogle」のメンバーにあいまいです。それは、私のコードはここでは、方向などを計算するGoogleの場所apiを使用しています。そして、ここにエラーのイメージがあります。あなたがhttps://github.com/varshylmobile/MapManager/blob/master/MapManager.swiftを使用していて、スウィフト3にそれを変換していると仮定すると、

@IBAction func ClickToGo(_ sender: AnyObject) { 
    if isValidPincode() { 
     mapManager.directionsUsingGoogle(from: txtFrom.text!, to: txtTo.text!) { (route,directionInformation, boundingRegion, error) ->() in 

      if(error != nil){ 
       print(error) 
      } 
      else{ 
       let pointOfOrigin = MKPointAnnotation() 
       pointOfOrigin.coordinate = route!.coordinate 
       pointOfOrigin.title = directionInformation?.object(forKey: "start_address") as! NSString as String 
       pointOfOrigin.subtitle = directionInformation?.object(forKey: "duration") as! NSString as String 

       let pointOfDestination = MKPointAnnotation() 
       pointOfDestination.coordinate = route!.coordinate 
       pointOfDestination.title = directionInformation?.object(forKey: "end_address") as! NSString as String 
       pointOfDestination.subtitle = directionInformation?.object(forKey: "distance") as! NSString as String 

       let start_location = directionInformation?.object(forKey: "start_location") as! NSDictionary 
       let originLat = start_location.object(forKey: "lat")?.doubleValue 
       let originLng = start_location.object(forKey: "lng")?.doubleValue 

       let end_location = directionInformation?.object(forKey: "end_location") as! NSDictionary 
       let destLat = end_location.object(forKey: "lat")?.doubleValue 
       let destLng = end_location.object(forKey: "lng")?.doubleValue 

       let coordOrigin = CLLocationCoordinate2D(latitude: originLat!, longitude: originLng!) 
       let coordDesitination = CLLocationCoordinate2D(latitude: destLat!, longitude: destLng!) 

       pointOfOrigin.coordinate = coordOrigin 
       pointOfDestination.coordinate = coordDesitination 
       if let web = self.drawMap { 
        DispatchQueue.main.async { 
        self.removeAllPlacemarkFromMap(shouldRemoveUserLocation: true) 
        web.add(route!) 
        web.addAnnotation(pointOfOrigin) 
        web.addAnnotation(pointOfDestination) 
        web.setVisibleMapRect(boundingRegion!, animated: true) 
        print(directionInformation) 
        self.tableData = directionInformation! 
        } 
       } 
      } 
     } } 
}

、APIは以下の署名がありますので、

func directionsUsingGoogle(from:NSString, to:NSString, 
    directionCompletionHandler:DirectionsCompletionHandler) 

func directionsUsingGoogle(from:CLLocationCoordinate2D, to:CLLocationCoordinate2D, 
    directionCompletionHandler:DirectionsCompletionHandler) 

func directionsUsingGoogle(from:CLLocationCoordinate2D, to:NSString, 
    directionCompletionHandler:DirectionsCompletionHandler) 

お知らせNSString、：

mapManager.directionsUsingGoogle(
    from: txtFrom.text! as NSString, 
    to: txtTo.text! as NSString, 
    directionCompletionHandler: {(
     _ route:MKPolyline?, 
     _ directionInformation:NSDictionary?, 
     _ boundingRegion:MKMapRect?, 
     _ error:String?) in 
     ... 
    } 
)
