How to show Cluster for MKPolyline with geojson da

问题:

I am loading Mapview with geojson data. It contains 7000 data in that geojson file. Even I loaded that data into Mapview. Its loaded fine, but, the problem is mapview getting freezing/stucking for few seconds while zoomin/zoomou So, its getting very bad user experience.

Even, I loaded the data in background thread, still mapview getting freeze.

After I read few forums, we can load clusters to avoid this kind freeze UI issue for mapview, but, I did not found for geojson data loading with clusters and for MKpolylines. I am showing in my mapview Polylines and Annoations by loading 2 geojson files to MKMapview.

Anyone can suggest me, how to show clusters for MKPolylines and Annotations by loading with geojson files.

For more info please check this following link which I have raised query for my mapview freezing issue.
