How to cache a specific portion of a UIMapView

I'd like to have the imagery of a UIMapView for a whole city cac开发者_开发问答hed and shipped with my app to have the user actually see a map when they are offline.

Is there a way to do this?

Cheers!

While this is technically possible (you'd use Google's map API rather than using a specific iOS API) it's actually against the T&C's of the service. There are a few apps that use OpenStreetMap for this purpose. It has the CC-BY-SA licence.

Not within Google's terms of service. See section 10.3.
