i dont think so .. it will only be possible if you load the data again which means the uipicker(all same instance) with loaded with same data

of course this is possible. Just switch to another model that holds the data that is used in the picker.

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
   if (myCurrentEditingValue == MyCountryValue) {
        return ...
   }
   else if (myCurrentEditingValue == MyCityValue) {
        return ...
   }
   return nil;
}

- (IBAction)startEditingCountryField {
    myCurrentEditingValue = MyCountryValue;
    [picker reloadAllComponents];
}

You should get the idea.
