导航控制器干扰TabBar控制器

Question

I have a menu, which is just a tableview on a tab. When you select one of the table cells it segues to a viewcontroller that is embedded in a navigation controller. i have added a 'Done' button to this navigation controller and created a segue back to the menu. however now the menu doesn't show the tabBar and it now shows a navigation bar with a 'Back" button on it.

This is the menu (part of tab bar) just a table view

This is the pages shown when clicking tableview cell

This is the menu again after clicking 'Done'

when clicking done i wanted it to go back to the menu as it was shown in the first screenshot. i was trying to use the interface builder for this but guess i could create a class and go back to the menu via code.

Any ideas how to fix this?

----- EDIT -----

This is support page without 'Done' button

this is the flow layout, sorry its messy working on small screen laptop atm

Answer 1

You should use the "Show (eg Push)" segue and not "Push". This allows it to show itself correctly in the stack.

Using "Push" requires that the existing screen exists inside a navigation controller, which it doesn't on the first load. By using "Push" it is moving the controller into a navigation controller stack which leaves you with the navigation bar after pressing done.

By using the "Show (eg Push)" segue option, the system will chose to use a modal presentation or a navigation controller push based on your current view hierarchy.

Show (eg Push):

Note: if your view is shown using a Model presentation you need to use

[self dismissViewControllerAnimated:YES completion:nil]; 

and not

[self.navigationController popViewControllerAnimated:YES]; 

You can do a quick check to choose the correct method:

if (self.navigationController) {
    [self.navigationController popViewControllerAnimated:YES];
}
else {
    [self dismissViewControllerAnimated:YES completion:nil];
}

This will allow you to show the screen in multiple ways without having to do any additional checks

I just realised you did not have a Navigation bar on your Menu Tab. All you need to do is embed in a navigation controller. Let me know if it does not work.

override  func tableView(_ tableView: UITableView, didSelectRowAt
 indexPath: IndexPath){
    if(indexPath.row == THE_ROWNUMBER_OF_YOUR_SUPPORT_PAGE){
        let displaySupportPage = self.storyboard?.instantiateViewController(withIdentifier: "SuppportPage") as! ChooseSalonTVC
        self.navigationController?.pushViewController(displaySupportPage, animated: true)
    }

 }
