Hi!

Really cool clustering you have implemented. However, I'm looking for a way to remove all annotations from the cluster before I add new ones in order to avoid duplicates.

I tried to implement this by adding this in QuadTree.swift

func removeAllAnnotations(){
        rootNode.removeAllAnnotations()
    }

And this seems to work... kinda, but not if I call it when adding annotations.

 public func addAnnotations(annotations:[MKAnnotation]) {
        lock.lock()
        removeAllAnnotations()
        for annotation in annotations {
            tree.addAnnotation(annotation)
        }
        lock.unlock()
    }

    func removeAllAnnotations(){
        tree.removeAllAnnotations()
    }

I still get duplicates this way. And even if I add the removeAllAnnotations() call to after the tree.addAnnotation(annotation) call I still get plenty of annotations in my map.

Any idea how to best implement this? I basically just want to remove all clustered annotations before adding new ones.

It would be great to have animations when a couple of pins are being clustered into a single cluster pin or when a cluster pin gets exploded into a couple of pins.

See:
Apple Example: PhotoMap

This might be of interest, too:
CCHMapClusterController

removeAnnotation would find the given annotation leaf in the quadtree and remove it.

This would make it possible to

1. remove annotations from the quadtree
2. replace annotations in the quadtree (i.e. for moving map objects) via subsequent calls to removeAnnotation & addAnnotation

I have problem when trying to add same coordinates many time but in example show only 440 cluster.
To re produce the bug :
in Example/ViewController.swift
line 29: let numberOfLocations = 1000
line 52: a.coordinate = CLLocationCoordinate2D(latitude: 15.415599822998047, longitude: 101.57099914550781)

and then compile and run.

the map show only 440 annotation

Hi, this is a really nice plugin. Everything seems to work except for the AnnotationClusterViewOptions. The code below worked back when i used the FBAnnotationClusteringSwift but can't figure out why it isn't working here.

Here's a snippet from my viewForAnnotation method that handles the annotation cluster

case let cluster as AnnotationCluster:
reuseId = "Cluster"
if let clusterView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? AnnotationClusterView {
    clusterView.reuseWithAnnotation(cluster)
    return clusterView
} else {
    let options = AnnotationClusterViewOptions(smallClusterImage: "cluster_small", mediumClusterImage: "cluster_medium", largeClusterImage: "cluster_large")
    let clusterView = AnnotationClusterView(annotation: cluster, reuseIdentifier: reuseId, options: options)
    return clusterView
}

Thanks!
