I'm using an annotation customization in my mapkit project (swift 3) to show more than one annotation (pin) on the map. It is showing and you can click annotationn, but only the first time. So I can click and annotate and open it, only if I click anywhere on the map and then re-click the annotation again. Has anyone been through this kind of help? Thanks in advance.
Here are the functions I'm using:
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is MKUserLocation
{
return nil
}
var annotationView = self.map.dequeueReusableAnnotationView(withIdentifier: "Pin")
if annotationView == nil{
annotationView = AnnotationView(annotation: annotation, reuseIdentifier: "Pin")
annotationView?.canShowCallout = false
}else{
annotationView?.annotation = annotation
}
if (indexPin > 0) {
indexPin = indexPin - 1
let pin : PinAnnotation = pinAnotationList[indexPin]
annotationView?.image = UIImage(named: pin.imageName)
}
return annotationView
}
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView)
{
if view.annotation is MKUserLocation
{
return
}
let pin = view.annotation as! PinAnnotation
if pin.userType == "O" {
if (currentLatitude == 0 || currentLatitude2 == 0) {
self.showAlert(self, message: "It's necessary to set origin and destiny addresses")
return
}
AppVars.DriverId = pin.userId
AppVars.VehicleId = pin.vehicleId
AppVars.LatitudeDriver = pin.coordinate.latitude
AppVars.LongitudeDriver = pin.coordinate.longitude
performSegue(withIdentifier: "callDriverPopupSegue", sender: self)
}
else {
let customView = (Bundle.main.loadNibNamed("AnnotationView", owner: self, options: nil))?[0] as! CustomCalloutView
var calloutViewFrame = customView.frame;
let point = CGPoint(x: calloutViewFrame.size.width/2 + 15,y :calloutViewFrame.size.height - 10)
calloutViewFrame.origin = point
customView.frame = calloutViewFrame;
customView.titleLabel.text = pin.title
view.addSubview(customView)
}
}
func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView) {
if (view.isKind(of: PinAnnotation.self))
{
for subview in view.subviews
{
subview.removeFromSuperview()
}
}
if (view.isKind(of: AnnotationView.self))
{
for subview in view.subviews
{
subview.removeFromSuperview()
}
}
}
