iOS 7 MapKit Crash: EXC_BAD_ACCESS in [VKRasterOverlayTileSource invalidateRect:level:]

Question

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.

Exception Type: EXC_BAD_ACCESS 

Code: KERN_INVALID_ADDRESS at 0x291707628

Answer 1

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...
