Storyboard Segue From View Controller to Itself

Question

I am trying to make a mechanism to drill down a file / folder list. The idea is to show the same file list view controller every time the user selects a folder, and show a f

Answer 1

Instead of performing a segue to the same controller, you can instantiate a view controller (the same one) from storyboard, and then push that onto the navigation controller.

Answer 2

Interface Builder approach: Just segue to a storyboard reference which refers back to the presenting view controller.

Answer 3

In IOS 6, there is a cleaner solution than using a phantom button. You can still define the segue from the table cell to the view controller, and look at the sender to cancel the automatically triggered segue:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    //storyboards should use segues and override prepareForSegue instead
    //but here we need custom logic to determine which segue to use
    id item = [self.fetchedResultsController objectAtIndexPath:indexPath];
    if (item meets condition) {
        [self performSegueWithIdentifier:@"segue1" sender:self];
    } else {
        [self performSegueWithIdentifier:@"segue2" sender:self];
    }
}

- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
    //ignore segue from cell since we we are calling manually in didSelectRowAtIndexPath
    return (sender == self);
}

Hope this helps.

I found that you can create multiple prototype cells.

Than you can link every cell (in the Storyboard) to a different View.

Something like this:

NSString *CellIdentifier = @"Cell"; 
if (Condition2 ){
CellIdentifier = @"Cell2"; } 
if (Condition3 ){
CellIdentifier = @"Cell3"; }

If you are using a navigation controller you need to push the ViewController into the nav stack. In this example, i named my ViewController "VDI" in my Storyboard ID setting.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
YourVC *dest = [storyboard instantiateViewControllerWithIdentifier:@"VDI"];
[self.navigationController pushViewController:dest animated:YES];

If you don't want the NavigationController to keep adding itself into your "Back" history you can pop the stack before adding to it like so.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
YourVC *dest = [storyboard instantiateViewControllerWithIdentifier:@"VDI"];
UINavigationController *navController = self.navigationController;
[navController popViewControllerAnimated:NO];
[navController pushViewController:dest animated:YES];

Answer 6

Here's how you can push another instance of the current view controller without defining a segue or hardcoding its own identifier:

SameViewController *same = [self.storyboard instantiateViewControllerWithIdentifier: self.restorationIdentifier];
[self.navigationController pushViewController: same animated: YES];

You just need to set the Restoration ID to be the same as Storyboard ID (there's a checkbox for that in IB).
