Question

I’m working in an app with 1 master table view.

There are cells leading to a detailview after going through 1, 2 or 3 tableview levels based on certain parameters (for example BOOL sub).

The app behaviour is as follows:

UINavigationController -> UITableViewController (sub == YES) -> UITableViewController (sub == NO)-> DetailViewController

UINavigationController -> UITableViewController (sub == YES) -> UITableViewController (sub == YES) -> UITableViewController (sub == NO) -> DetailViewController

And so on (max 3 levels).

Someone knows how to do that (using storyboard) with just 1 UITableViewController?

Answer 1

First, define two “generic” segues called "toDetail" and "toNextLevel" in the story board from your table view controller. One segue should lead to the detail controller; the other one should lead back to the table view controller. Then, implement the tableView:didSelectRowAtIndexPath: method with a condition that moves you to the next level when there is one, or to the detail screen when there is no next level:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    if ([myModel rowHasNextLevel:indexPath.row]) {
        [self performSegueWithIdentifier:@"toNextLevel" sender:self];
    } else {
        [self performSegueWithIdentifier:@"toDetail" sender:self];
    }
}
