A pin should be dropped at the place - ( i can do that )

A pin title should be with City & State name - ( i can't do )

Answer 1

You can get both the city and state name by querying this web service:

NSString *nameString = [NSString stringWithFormat:@"http://ws.geonames.org/findNearestAddress?lat=%f&lng=%f",latitude,longitude];

This will return the full nearest address in xml format with you can then parse to get city ans state information
