iOS 7 Reverse Geocoding Using Mapkit

Question

I am making an app with a map that shows the location that you type in a text field, also if you move around the map it displays on the text field the address of the location that you are looking at.

When I move around the map it display the address in the text field and shows only the street, but I was wondering if it is possible to show the address as is used in Colombia, for example: Carrera 1 # 18A - 12.If you type the address like the example in the text field it works and it founds it in the map, but does not display the address in the text field as I want.

Here is the code I am using.

If somebody can help me i would really appreciate it. Thanks

Here is the code I use to get the full address, if I understood your question correctly.

[geocoder reverseGeocodeLocation:touchLocation completionHandler:^(NSArray *placemarks, NSError *error) {
    if (!error) {
    CLPlacemark *placemark = [placemarks objectAtIndex:0];

    // Update annotation with address
    self.person.address.state = placemark.administrativeArea;

    self.person.address.city = placemark.locality;
    NSString *placemarkAddress;
    //Accounts for the possibility of the number or street being null
    if (placemark.subThoroughfare && placemark.thoroughfare){
        placemarkAddress = [NSString stringWithFormat:@"%@ %@",placemark.subThoroughfare, placemark.thoroughfare];
    }
    else if (placemark.thoroughfare){
        placemarkAddress = placemark.thoroughfare;
    }
    self.person.address.street1 = placemarkAddress;
    self.person.address.zip = placemark.postalCode;
    }
    else {
        //Error
    }
}];
