问题
I have an unreproducible crash on iOS 7 only. I'm making heavy use of MKOverlayRenderer to draw shapes on the map. This crash does not happen on iOS 6.
Any ideas of what this might be related to will be useful.

I found my problem. Might be that it solves yours too... In dealloc, remove all of the MapViews overlays and the crash should be fixed...
