I'm looking for offline maps for IPhone.
For now I've discovered Route-me and CloudMade.
CloudMade doesn't have build in functionality for offline maps. There is an option to setup CloudMade to work offline but other question how to get a map you need.
Route-me works with MbTiles format. There is option to download osm file(From OpenStreetmap) and convert it to MbTiles file.
My questions: Are there sdk for IPhone that support offline maps? And how to get maps suitable for this sdk?
