How to use Offline Cloudmade Maps in an iPhone App

Question

I’ve looked through the posts on the Cloudmade site here and I get some of it, but not all. I've posted the question below, but haven't had the help I need, so I thought I'd ask the question here.

I can see that I need to:

• download the tiles for the required area to my Mac (but can’t see how to do this)
• convert these to a sqlite database using the map2sqlite utility, changing the code to output the tiles to a table called “ZCACHE”, not “tiles”
• Copy the DB to the Application Bundle
• insert some code to copy this DB on first run, from the Application Bundle to the Documents Directory
• Somehow get App to use this DB and not an online one – I can’t see how that’s done.

Any help would be warmly welcomed,

Chris.

Answer 2

The best solution for me to have iPhone offline maps is:

1.- Generate your own maps with TileMill and then export to MBTiles format.

2.- Get the mbtiles-ios-example and use the MBTiles file you just generated. In order to compile it, you need to download Route-Me and add it to the project.

Now, there is another option (not for free): Mapbox.
