title: MKMapView clustering if too many Map Pins nearby
body: <p>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).</p>
  
  <p>It doesn't matter to zoom in because they are still overlapping. I've already tried <a href="https://github.com/applidium/ADClusterMapView" rel="noreferrer">https://github.com/applidium/ADClusterMapView</a> (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.</p>
  
  <p>I'm working on an app with an offline-db so a server-side solution is not an option.</p>
  
  <p>thank you for your help!</p>
