How to find latitude longitude from the address?

I am us开发者_StackOverflowing MapKit for google map? How to find latitude longitude using address?

however, you can do it by calling this web services (plain http + json, use the TouchJSON library for parsing the response or json-framework): http://code.google.com/intl/it-IT/apis/maps/documentation/geocoding/index.html
