Yes. Since the data source and delegate methods provide a reference to the tableview, you can simply check if it is equal to the first or the second table you have.
Example:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if ([tableView isEqual:_firstTable]) {
// Do something
}
else { // tableView == _secondTable
// Do something else
}
}
