Im using Map Kit and Core Location now and need to to get location information from zip code or city/state. Is there any way to do it?

You can use the CLGeocoder class which supports converting an address to a coordinate, and the reverse. For example:

[geocoder geocodeAddressString:@"<postcode here>"
             completionHandler:^(NSArray* placemarks, NSError* error){
                 for (CLPlacemark* aPlacemark in placemarks)
                 {
                     // Process the placemark.
                 }
}];

There are a bunch of different methods you may want to use. You can limit the search to a particular region, for example.
