Caching maps

[phillipie99]

I am setting up a map application and would like to know how to load the maps from a file or a cache to speed up loading after parts of the map have already been downloaded once.

If you're using the map kit, you can't. It's a big opaque class that does all kinds of things under the hood, and us lowly app developers aren't allowed to muck with it's innards.

You will have to use one of the third party open source mapping libraries for things like that. There is a decent one called route-me that links to the Google map server, but it is a lot of work to use it compared with the iOS map-kit, and it's kind of screwy internally.
