MKPolyLineRenderer changes color without removing the overlay

I am developing an application that almost reproduces the behavior of Apple applications. When I touch a route, I need to change its color to blue and change other colors to gray. Is there an effective way to do this without removing the overlays and adding them again? Thanks.

Yes:

  • Make sure your annotation view has enabled = YES .

  • Embed -[MKMapViewDelegate mapView:didSelectAnnotationView:] .

  • In this callback, get view and change its properties.
