Is there a way to implement standalone geocoding in standalone sqlite database of openstreetmaps database in iPhone?

In my iPhone app, I displayed openstreetmaps tiles using map2sqlite. Now I want to implement gecoding functions, such as displaying a marker at a specific location in an offline map. Any ideas?

The mapping and geocoding of a well map are very different requirements for the structures of a geospatial dataset.
AFAIK there is currently no geocoding for the iPhone, just a Nominatim server .

If you are not afraid of the amount of data, you can use http://www.geonames.org as a starting point for your own library. Or, you analyze all the processing that Nominatim does for OSM data to isolate places, addresses, roads, and borders (which is complex and needs to be pre-cleared).
