How to find city name with respect to the zip code through iphone applications

Question

Can any one help me in finding the city name in the map when I give zipcode through iPhone application.

Answer 1

Created a little native tool that looks up city, state, and lat/long without using the network connection. Has a rather large (1.9MB) SQLite database to pull from, so don't include this if you can just query Google or another online API.
