Hi all,

if you're deprecating iOS6 then the solution might be to just implement

[MKOverlay canReplaceMapContent]

and return YES. This effectively prevents iOS from loading Apple map
content:

https://developer.apple.com/library/ios/documentation/MapKit/Reference/MKOverlay_protocol/#//apple_ref/occ/intfm/MKOverlay/canReplaceMapContent

As for the MKTileOverlay, that would be an option as well, I'm just not
sure how efficient it is for caching OSM content - the documentation is
silent on that point:

https://developer.apple.com/library/prerelease/ios/documentation/MapKit/Reference/MKTileOverlay_class/index.html

And as I already have the drawing code we could go with that.

Best, Ulf
