MKMapView clustering if too many Map Pins nearby

I'm wondering if any of you knows a method (library, category, etc.) to cluster iOS MapAnnotations if there are many of them at the same location (e.g. 4 pieces in about 10m).

It doesn't matter to zoom in because they are still overlapping. I've already tried https://github.com/applidium/ADClusterMapView (and sombe other libs) but all of them are made for showing clusters in zoom-out-scenarios. None of them really respect the distance between annotations when zoomed in.

I'm working on an app with an offline-db so a server-side solution is not an option.

thank you for your help!

You don't need 3rd party framework's anymore. iOS 11 has native clustering support.

You need to implement mapView:clusterAnnotationForMemberAnnotations: method.

Get more details in the Apple example: https://developer.apple.com/sample-code/wwdc/2017/MapKit-Sample.zip

You should have a look into CCHMapClusterController project, looks exactly like something you are looking for.

One alternative is the MapBox iOS SDK, which is an open source (BSD) library replicating MapKit behavior. It does both annotation clustering and offline map layers.
