indexPath has no value in Table View

I have a table view displaying a list of contacts and when you click a cell, a detail view controller pops up with labels showing the contact name, number, fax, and address. My problem is that every time I click a cell, the first value in the plist pops up no matter which cell i click. I found my error in indexPath when NSLog(@"%@",indexPath); returned null everytime. I think the problem is in this method but it looks the same in other classes and works fine.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"showCountyInfo"])
    {
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        NSLog(@"%@",indexPath);
        TSPBookCoverViewController *destViewController = segue.destinationViewController;
        destViewController.countyName = [[self.books objectAtIndex:indexPath.row] objectForKey:@"Name"];//error
        destViewController.phoneName = [[self.books objectAtIndex:indexPath.row] objectForKey:@"Phone"];
        destViewController.faxName = [[self.books objectAtIndex:indexPath.row] objectForKey:@"Fax"];
        destViewController.addressName = [[self.books objectAtIndex:indexPath.row] objectForKey:@"Address"];
    }
}

When I enter integers instead of indexPath.row, it works like it should, so the problem is here I just can't find it. Sorry if it's obvious I've tried looking for awhile now!

Edit: Here is didSelectRowAtIndexPath method:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

    // Perform Segue
    [self performSegueWithIdentifier:@"showCountyInfo" sender:self];   
}

The issue is with the following code:

[tableView deselectRowAtIndexPath:indexPath animated:YES];

You are deselecting the cell inside the didSelectRowAtIndexPath: method. So the indexPathForSelectedRow will always return nil

Best way for you to resolve it is to get the Dictionary from self.books array in

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

and then perform the segue and get values from that dictionary in prepareForSegue
