Question

So I have the didSelectRowAtIndexPath method into a UITableViewController.

The TableView goes to a UIViewController which is controlled by a NavigationController.

I want to send the indexPath.row to the class called by the NavigationController, is there any way to send a parameter to another class?

My app scheme is:

TabBarController —> NavigationController —> TableViewController —> UIViewController

If you are using storyboard:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    UITableViewCell *cell = sender;
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
    {
        // Get reference to the destination view controller
        YourViewController *vc = [segue destinationViewController];
        NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];

        // Pass any objects to the view controller here, like...
        [vc setIndexPath:indexPath];
    }
}

else

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row == 0) {
        YourViewController *vc = [[YourViewController alloc] initWithNibName:@"YourViewController" bundle:nil];
        [vc setIndexPath:indexPath];
    }

}
