How to identify how many annotations does a cluster annotation has

Hi

I'm trying to zoom in when the user taps on a cluster annotation, and now I did that I want to zoom in differently depends on how many annotations does the cluster annotation that I tapped has clustered.

Thanks in advance

I found it out!

Inside didselectannotation I put these lines of code:

if view.annotation!.isKindOfClass(FBAnnotationCluster)
        {
            let pinToZoomOn = view.annotation as! FBAnnotationCluster
//this is for getting the number of clustered annotations
            print(pinToZoomOn.annotations.count)

//Then depends of how many there are you can zoom differently            
            let span = MKCoordinateSpanMake(0.010, 0.010)

            let region = MKCoordinateRegion(center: pinToZoomOn.coordinate, span: span)
            mapView.setRegion(region, animated: true)
        }
