custom annotation class about clusterkit HOT 7 CLOSED

Hi,

CKAnnotation inherits from MKAnnotation, you just need to use CKAnnotation:

class MyAnnotations: NSObject, CKAnnotation{
    
    weak public var cluster: CKCluster?
    
    var coordinate: CLLocationCoordinate2D
    var title: String?
    var subtitle: String?
    var name: String?
    var size: String?
    var user: String?
    var owner: String?
    var image: String?
    var latLoc: Double?
    var lonLoc: Double?
    var itemId: String?
    
    init(coordinate: CLLocationCoordinate2D) {
        self.coordinate = coordinate
    }
}

Then, you have to assign an array of annotation to the cluster manager, not a single one.

Thnx mcaxep, i made an array:
var newArray:[Annotation] = []
then i add annotations to that array:
self.newArray.append(annotation)

but when i do this i get the same error...

Can you help me?

I cannot reproduce your issue in the swift exemple project, I tried with:

mapView.clusterManager.annotations = [MyAnnotations(coordinate: CLLocationCoordinate2D(latitude: 48.853, longitude: 2.35))]

from clusterkit.

Ok i found the problem ( var newArray:[Annotation] = []) had to be var newArray:[MyAnnotations]

Thnx!

Sorry again, i'm quite there but.. in the function:

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
      
      let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "annotation") ??
          MKAnnotationView(annotation: annotation, reuseIdentifier: "annotation")
      
      if let cluster = annotation as? CKCluster {
          
          if cluster.count > 1 {
              annotationView.canShowCallout = false
              annotationView.image = UIImage(named: "cluster")
          } else {
           annotationView.canShowCallout = true
           annotationView.image = UIImage(named: "marker")

i added:

let MyAnnotations = annotation as! MyAnnotations
if MyAnnotations.user == userID {.........

because i've to access MyAnnotation properties but compiler shows me this error:

Could not cast value of type 'NSKVONotifying_CKCluster' (0x608000106540) to 'app.MyAnnotations' (0x1071d61f8).

from clusterkit.

Yes because the annotation parameter is indeed a CKCluster, that cluster represents a group of annotation. These annotations are accessible in the annotations property of the cluster.

from clusterkit.

can you make me a simple example of how can i access them please? I really need to access properties like size that is defined MyAnnotation class, sorry about being stressing but i'm too to understand well your code..
