Ios – Xcode 6 – Push segue to same view controller

iosuistoryboardxcodexcode6

I have a table view controller and tapping on a cell can trigger one of many different types of push segues based on the type of data in the cell. The identifier of the correct segue is determined in tableView:didSelectRowAtIndexPath: and then the segue is triggered with self.performSegueWithIdentifier:

For one of those segues, I'd like to push another instance of the same view controller on to the navigation stack. Is this possible without having to drag a new view controller object of the same type onto the storyboard? So far, I have only been able to wire up a segue to the same view controller if I Ctrl + Drag from the table cell to the view controller. This is not what I want.

As suggested, I don't think a segue will work. Instead you can push a new instance of the same view controller programmatically, which will have the same effect as performing the segue. The difference is that segue delegate methods like prepareForSegue won't be called.

- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    MyViewController *vc = [[MyViewController alloc] init];
    [self.navigationController pushViewController:vc animated:YES];
}

Ios – Storyboard Segue From View Controller to Itself

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];
