MKAnnotation보기 수행 방법지도에서 핀 선택시 표시

Question

내 MKAnnotation보기를 열지 않은 핀을 클릭 할 때 문제가 있습니다. 이것은 내 코드입니다. 이것을 확인하고 해결책을 좀주세요.

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) { 

    if let annotationTitle = view.annotation?.title 
    { 
     let annotationIdentifier = "AnnotationIdentifier" 
     var annotationView = MKAnnotationView() 

     annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier) 
     annotationView.annotation = annotation 

     let dictList = self.arrPin.object(at: annotationView.tag) as? NSDictionary 


     viewPopUp = UIView(frame: CGRect(x: (annotationView.frame.origin.x) - 128, y: (annotationView.frame.origin.y) - 59, width: 250, height: 60)) 



     let lblCategory = UILabel(frame: CGRect(x: imageView.frame.origin.x + 72, y: lblName.frame.origin.y + 25, width: imageView.frame.size.width - 30, height: 18)) 
     lblCategory.textColor = UIColor(red: 151/255, green: 151/255, blue: 151/255, alpha: 1.0) 
     lblCategory.textAlignment = .natural 
     lblCategory.font = UIFont(name: "HelveticaNeue-Light", size: 14) 
     lblCategory.text = txtSearch.text 


     viewPopUp.addSubview(lblCategory) 

     annotationView.addSubview(viewPopUp) 
    } 
}

지도에서 적절한 주석보기를 열었습니다. 주석 프레임을주고 핀, 그 시간 팝업보기 프레임을 선택하십시오.

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? { 

     guard !(annotation is MKUserLocation) else { 
      return nil 
     } 


     // Better to make this class property 
     let annotationIdentifier = "AnnotationIdentifier" 
     var annotationView = MKAnnotationView() 
     annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier) 
     annotationView.frame = CGRect(x: annotationView.frame.origin.x, y: annotationView.frame.origin.y, width: 80, height: 200) 
     annotationView.annotation = annotation 
     annotationView.tag = index 
     index += 1 

     let imageViewPin = UIImageView(frame: CGRect(x: 0, y: 0, width: 30, height: 40)) 
     imageViewPin.center = CGPoint(x: annotationView.center.x, y: annotationView.center.y - 11) 
     imageViewPin.image = UIImage(named: "green_pin") 
     annotationView.addSubview(imageViewPin) 

     return annotationView 
    } 

    func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) { 

     debugPrint(view.tag) 
     let overlays = self.mapVW.overlays 
     self.mapVW.removeOverlays(overlays) 


     if viewPopUp != nil { 
      viewPopUp.removeFromSuperview() 
      for item in viewPopUp.subviews 
      { 
       item.removeFromSuperview() 
      } 
     } 

     if arrPin.count >= view.tag { 
      let dictList = self.arrPin.object(at: view.tag) as? NSDictionary 
      viewPopUp = UIView(frame: CGRect(x: -98, y: 10, width: 250, height: 60)) 
      view.addSubview(viewPopUp) 

      let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: viewPopUp.frame.size.width, height: viewPopUp.frame.size.height)) 
      imageView.image = UIImage(named: "ic_mappopupbackground") 
      imageView.contentMode = .scaleAspectFit 

      let imgCar = UIImageView(frame: CGRect(x: imageView.frame.origin.x + 25, y: 9, width: 30, height: 20)) 
      imgCar.image = UIImage(named: "ic_car") 
      imgCar.contentMode = .scaleAspectFit 


      let lblMin = UILabel(frame: CGRect(x: imageView.frame.origin.x + 18, y: 33, width: 45, height: 15)) 
      lblMin.textColor = UIColor.white 
      lblMin.textAlignment = .center 
      lblMin.font = UIFont(name: "HelveticaNeue-Light", size: 11) 

      let totalDist = distance(lat: dictList?.value(forKey: "lat") as! String, long: dictList?.value(forKey: "lon") as! String) 
      lblMin.text = "\(totalDist) mi" 

      let lblName = UILabel(frame: CGRect(x: imageView.frame.origin.x + 70, y: 5, width: 150, height: 25)) 
      lblName.textColor = UIColor.black 
      lblName.textAlignment = .natural 
      lblName.adjustsFontSizeToFitWidth = true 
      lblName.numberOfLines = 0 
      lblName.lineBreakMode = .byCharWrapping 
      lblName.font = UIFont(name: "HelveticaNeue-CondensedBold", size: 18) 
      lblName.text = dictList?.value(forKey: "name") as? String 

      let lblCategory = UILabel(frame: CGRect(x: imageView.frame.origin.x + 72, y: lblName.frame.origin.y + 25, width: imageView.frame.size.width - 30, height: 18)) 
      lblCategory.textColor = UIColor(red: 151/255, green: 151/255, blue: 151/255, alpha: 1.0) 
      lblCategory.textAlignment = .natural 
      lblCategory.font = UIFont(name: "HelveticaNeue-Light", size: 14) 
      lblCategory.text = txtSearch.text 


      viewPopUp.addSubview(imageView) 
      viewPopUp.addSubview(imgCar) 
      viewPopUp.addSubview(lblMin) 
      viewPopUp.addSubview(lblName) 
      viewPopUp.addSubview(lblCategory) 
      // viewPopUp.addSubview(btnRoute) 

      viewPopUp.isUserInteractionEnabled = true 
      let tap = UITapGestureRecognizer(target: self, action: #selector(btnRouteView(sender:))) 
      self.selectIndex = view.tag 
      viewPopUp.addGestureRecognizer(tap) 
     } 

    }
