Annotations showing wrong image - swift

Question

Is there any way that annotations might show other images then it should supose ? Is it a way to fix that ?
I've got a werid problem. After my clusters going to evolve to the single annotations then after updating ( zoom out - zoom in ) they images going to be diferent then it should be. After debuging it says that the color of the pin view image is the one which I suposed. Where I could hook up yet to see the exact data ? Maybe something after viewFor which get invoked.
Here is a logic how am I doing this.
The dictionary to knows witch model is on the top of the added annotations.
var dicAnnotations = [FBAnnotation : MyModel]()
Through the loop of [MyModel] i am appending data to the array of the [FBAnnotation] which is needed for saving them via FBClusteringManager. Then in the same time while the new annotation is added to the [FBAnnotation] I am adding
self.dicAnnotations[fbAnnotation] = objModel
to know which annotation have which object.
So as we know how I am soring the data of annotations, how Am I indexing them, lets have a look on the delegate of the MKMapView.
func mapView(_ mapView: MKMapView, regionDidChangeAnimated animated: Bool) {
DispatchQueue.global(qos: .userInitiated).async {
let mapBoundsWidth = Double(self.mapView.bounds.size.width)
let mapRectWidth = self.mapView.visibleMapRect.size.width
let scale = mapBoundsWidth / mapRectWidth
let annotationArray = self.clusterManager.clusteredAnnotations(withinMapRect: self.mapView.visibleMapRect, zoomScale:scale)
for ann in annotationArray {
if ann is FBAnnotation {
let a = ann as! FBAnnotation
print("Here u are , my color is : \(self.dicAnnotations[a]!.lineColor)")
}
}
DispatchQueue.main.async {
self.clusterManager.display(annotations: annotationArray, onMapView: self.mapView)
}
}
}
The for loop is for checking if the annotation is the one which should be - and it is!
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
var reuseId = ""
if annotation is FBAnnotationCluster {
reuseId = "Cluster"
var clusterView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId)
if clusterView == nil {
clusterView = FBAnnotationClusterView(annotation: annotation, reuseIdentifier: reuseId, configuration: FBAnnotationClusterViewConfiguration.default())
} else {
clusterView?.annotation = annotation
}
return clusterView
}
else {
let ann = annotation as! FBAnnotation
var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: "Pin")
pinView = MKAnnotationView(annotation: ann, reuseIdentifier: "Pin")
var modelType = dicAnnotations[ann]?.modelType
modelType = modelType?.modelTypeToString(modelType: modelType!)
let modelColor = dicAnnotations[ann]?.lineColor
let modelDirection = dicAnnotations[ann]?.withHeading360
print("\(modelType!)_\(modelColor!)")
pinView?.image = UIImage(named: "\(modelType!)_\(modelColor!)")?.rotated(by: Measurement(value: modelDirection!, unit: .degrees))
return pinView
}
}
How it looks in the stack call which I am able get :
Here u are , my color is : yellow
(lldb) po dicAnnotations[ann]
▿ Optional<MyModel>
▿ some : <Project.MyModel: 0x101b656f0>
(lldb) po dicAnnotations[ann]?.lineColor
▿ Optional<String>
- some : "yellow"
From :
// viewFor
... else { pinView?.annotation = ann } ...
Any ideas ? It shows me would say "random colored image".
Thanks in advance!
Solution
I've edited the delegate viewFor. Deleted the if pinView == null condition and else as well. Somehow it was not working like it suposed to.
