선택기의 이름이

Question

이라도 인식 할 수없는 선택기인데 사용자를 위치로 탐색하는 앱을 만들기 위해 MapBoxNavigation.swift을 사용하고 있습니다. 네비게이션이 시작될 때까지 모든 것이 잘 작동합니다. 그러나 탐색이 시작 MapBoxNavigation.swift이 NSNotification가 (어떻게 라이브러리 작품에 대한 설명서를 참조), 내가 쓴 옵서버이 오류 메시지를 던져 게시물 방출 때

app[49184:2686603] -[__NSCFConstantString navProgressDidChange:]: unrecognized selector sent to instance 0x1096dfdb0 

이 코드가를 그 게시물 MapBoxNavigation의 통지입니다. SWIFT :

//Primary ViewController, used for basically everything 
class ViewController: UIViewController, MGLMapViewDelegate, CLLocationManagerDelegate, UITextFieldDelegate, UIGestureRecognizerDelegate { 

    lazy var geocoder = CLGeocoder() 
    @IBOutlet weak var addressTextField: SearchTextField! //SearchTextField 
    @IBOutlet var mapView: MGLMapView! //MapView of MapBox

    let locationManager = CLLocationManager() 
    var searched = false

    var navigationStarted = false 


    //Getting the route object

     // This is needed.... i don't know why.. 
     mapView.delegate = self 

     //Delegate textField to Self 
     addressTextField.delegate = self 

     //Dismiss Keyboard on view Touch 
     //Looks for single or multiple taps. 
     let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard)) 
     self.mapView.addGestureRecognizer(tap) 
     //Delegate GestureRecognizer to self 
     tap.delegate = self 

     //Get the users current location and zoom to it 
     //Authorization stuff #privacy 
     self.locationManager.requestWhenInUseAuthorization()

    } 
func enableNavigationMode(){ 
     //Hiding some elements here 
     startNavigation() //Gets called properly 
    } 


    func navProgressDidChange(_ userInfo: NSNotification){ 
     print("depart") 
     print(userInfo) 
    } 

    func startNavigation(){ 
     //Get the JSON File via the MapBox API 
     var lat = locationManager.location?.coordinate.latitude 
     var long = locationManager.location?.coordinate.longitude 
     var depart = CLLocation(latitude: lat!, longitude: long!) 
     var start = Waypoint(coordinate: CLLocationCoordinate2D(latitude: lat!, longitude: long!)) 
     var end = Waypoint(coordinate: CLLocationCoordinate2D(latitude: Shared.shared.selectedParkhouse.latitude, longitude: Shared.shared.selectedParkhouse.longitude)) 

     var string = "https://api.mapbox.com/directions/v5/mapbox/driving-traffic/" + String(describing: long!) + "%2C" + String(describing: lat!) + "%3B" + String(describing: Shared.shared.selectedParkhouse.longitude) + "%2C" + String(describing: Shared.shared.selectedParkhouse.latitude) + ".json?access_token=mykey;)&steps=true" 

//Alamofire request works properly 
     Alamofire.request(string).responseData { response in 
      if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) { 

       let jsoninput = self.convertToDictionary(text: utf8Text)! 
       let jsonroute = (jsoninput["routes"] as! [AnyObject]).first as! [String:Any] 

       let route = Route(json: jsonroute, waypoints: [start, end], profileIdentifier: MBDirectionsProfileIdentifierAutomobileAvoidingTraffic) 
       let routecontroller = RouteController(route: route) 

       print("regging") 
       NotificationCenter.default.addObserver(RouteControllerAlertLevelDidChange, selector: #selector(self.navProgressDidChange(_:)), name: RouteControllerAlertLevelDidChange, object: routecontroller) 
       print("resuming") 
       routecontroller.resume() 
       print("updating(?)") 
       //Everything is fine until this function gets called and 
       //MapBoxNavigation.swift posts a Notification 

       routecontroller.locationManager(routecontroller.locationManager, didUpdateLocations: [depart]) 

      } 
     } 
    } 

내가 NotificationCenter 몇 팀을 사용 :

NotificationCenter.default.post(name: RouteControllerAlertLevelDidChange, object: self, userInfo: [ 
     RouteControllerAlertLevelDidChangeNotificationRouteProgressKey: routeProgress, 
     RouteControllerAlertLevelDidChangeNotificationDistanceToEndOfManeuverKey: userDistance, 
     RouteControllerProgressDidChangeNotificationIsFirstAlertForStepKey: isFirstAlertForStep 
     ]) 

이 필요한 모든 코드가 있어야한다 이미 도움을 청하러오고 있어요. 또한 다른 코드의 함수 이름과 매개 변수를 navProgressDidChange(userInfo: Notification) 이상의 매개 변수에서 현재 내 코드에있는 매개 변수로 시도했습니다. 나는 이런 일이 일어나는 이유를 모르며, 선택자가 나에게 잘 보이기 때문에 내 마음에 이해가 가지 않는다.

Answer 1

귀하의 구문이 올바르지 않습니다 : 당신은 통지 문자열 RouteControllerAlertLevelDidChange을 가입하고

NotificationCenter.default.addObserver(RouteControllerAlertLevelDidChange, selector: #selector(self.navProgressDidChange(_:)), name: RouteControllerAlertLevelDidChange, object: routecontroller) 

. self을 구독하려고하신 것입니다. 다음과 같은 오류 메시지가 표시됩니다.

app[49184:2686603] -[__NSCFConstantString navProgressDidChange:]: unrecognized selector sent to instance 0x1096dfdb0 

메시지를 상수 문자열로 보내려고한다고 불평하고 있습니다.
