Visualizzazione mappa personalizzata che si interrompe in initWithCoder in swift

Question

Ho un UITableViewCell, che ha una vista mappa come sottoview. Creata una classe personalizzata che gestisce tutte le azioni come aggiungere annotazioni, delegati ecc. E denominarla come CustomeMap.swift.

Dopo aver cambiato il nome della classe di vista della mappa per CustomeMap in cellulare Xib, applicazione va in crash a volte a initWithCoder metodo CustomeMap perché non ho implementato tale metodo. Più tardi ho aggiunto il metodo come segue:

import UIKit 
import MapKit 


protocol CustomeMapDelegate{ 
    func annotationClickEvent(info:NSDictionary?) 
} 

class CustomeMap: MKMapView,MKMapViewDelegate,CLLocationManagerDelegate { 

    var locationManager:CLLocationManager? 
    var delegate1:CustomeMapDelegate? 
    var tap:UITapGestureRecognizer? 

    required init(coder aDecoder: NSCoder) { 
     super.init(coder: aDecoder) 
    } 

    override func awakeFromNib() 
    { 
     if CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedAlways { 
      self.showsUserLocation = true; 
     } 
     else 
     { 
      locationManager = CLLocationManager() 
      locationManager?.delegate = self; 
      if locationManager!.respondsToSelector("requestAlwaysAuthorization") 
      { 
       locationManager?.requestAlwaysAuthorization() 
      } 
     } 
     self.delegate = self 
     self.userInteractionEnabled = true 
     tap = UITapGestureRecognizer(target: self, action: "calloutAction:") 
    } 
    func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) 
    { 
     if(status == CLAuthorizationStatus.AuthorizedAlways) 
     { 
      self.showsUserLocation = true; 
     } 
    } 

    func skipTouch() 
    { 

    } 

    class func createAnnotationForDict(temp:NSDictionary)->MyPointAnnotation 
    { 
     var venue = temp.valueForKey("venue") as? NSDictionary 
     var lat = venue!.valueForKey("latitude") as! Double 
     var lon = venue!.valueForKey("longitude") as! Double 
     var venueName = venue!.valueForKey("name") as! String 
     var dealName = temp.valueForKey("title") as? String 

     var coord:CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 0, longitude: 0) 
     coord.latitude = lat 
     coord.longitude = lon 
     var point = MyPointAnnotation() 
     point.userInfo = temp 
     point.coordinate = coord 
     point.title = dealName 
     point.subtitle = venueName 
     return point 
    } 

    func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! 
    { 
     if annotation is MKUserLocation { 
      return nil 
     } 

     let reuseId = "pin" 

     var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? MKPinAnnotationView 
     if pinView == nil { 
      pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId) 
      pinView!.canShowCallout = true 
      pinView!.animatesDrop = true 
      pinView!.pinColor = .Red 

      var assImg = UIImageView(image: UIImage(named: "r_arrow_g")) 
      assImg.frame = CGRectMake(0, 0, 16, 16) 
      assImg.contentMode = UIViewContentMode.ScaleAspectFit 
      pinView!.rightCalloutAccessoryView = assImg 

     } 
     else { 
      pinView!.annotation = annotation 
     } 
     return pinView 
    } 
    func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!) 
    { 
     if view.annotation.isKindOfClass(MKUserLocation){ return } 
     if let t1 = tap 
     { 

     } 
     else 
     { 
      tap = UITapGestureRecognizer(target: self, action: "calloutAction:") 
     } 
     view.addGestureRecognizer(tap!) 
    } 
    func mapView(mapView: MKMapView!, didDeselectAnnotationView view: MKAnnotationView!) 
    { 
     if view.annotation.isKindOfClass(MKUserLocation){ return } 
     view.removeGestureRecognizer(tap!) 
    } 
    func calloutAction(sender:UITapGestureRecognizer) 
    { 
     if(delegate1 != nil) 
     { 
      var view = sender.view as! MKAnnotationView 
      var ann = view.annotation as! MyPointAnnotation 
      delegate1!.annotationClickEvent(ann.userInfo) 
     } 
    } 

} 

ma ancora lo stesso problema.

Rimosso Subclassing concetto, appena creato un punto di vista e ha aggiunto MKMapView come sotto-vista. ma ora sto vedendo seguente incidente

Qualcuno si prega di aiuto per trovare quello che mi manca qui.

Answer 1

Sembra che la sottoclasse stia scherzando con i metodi di inizializzazione originali. I documenti per MKMapView dicono che non dovresti sottoclasse, ma usa il delegato per tutto ciò che ti serve.

Sebbene non sia necessario creare una sottoclasse della classe MKMapView, è possibile ottenere informazioni sul comportamento della visualizzazione della mappa fornendo un oggetto delegato.

Vi suggerisco di creare una sottoclasse personalizzata UIView, che contiene un MKMapView e agisce come suo delegato. Questo è il primo passo che farei per cercare di risolvere questo problema.
