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.
please check this tutorial, it can help - http://www.gisnotes.com/wordpress/category/sqlite3/.
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.
