Two segues from ViewController and ViewController in Navigation Controller

Question

I have ViewController (VC_1) that is embedded in NavigationController. In VC_1 there is TableView with cells and there is segue from each cell to ViewController with detailed info (VC_2).

So when I touch any cell in VC_1 I get VC_2 with navigation bar and back button.

What if I have separate ViewController VC_3 that is not inside NavigationController. It also has cells with segue to VC_2 with same identifier that VC_1's cell have. When I get to VC_2 from VC_3 I don't see navigation bar with back button. What are the ways to handle it?

Answer 1

You can place another navigation controller right behind the (VC_3)

Hope this was helpful :)

Answer 2

If you show VC_3 from VC_1 with Show (eg Push) segue the Navigation Bar must appear in the VC_3.

What if I have separate ViewController VC_3 that is not inside NavigationController.

From here I understand that you don't want a Navigation Bar on VC_3. So, you can hide the navigation bar in the viewWillAppear of VC3 and show it again in the viewWillDissappear like in this answer:

Then, if you do the segue from VC_3 to VC_2 with Show (eg Push) you will have the Navigation on VC_2 with no problems.

If after this it still not working, check that you are creating well the cell in VC_3 using the dequeueReusableCell withIdentifier method.

Answer 3

Add in a new navigation controller to your story board. Now, change the segues like this:

Vc_1 -> new navigation controller --> vc_3

If tat doesn't make sense this is what i mean, change the segue that is currently going from vc1 to vc3 and make it go to a new navigation controller and then connect that navigation controller and make vc3 its root view controller.

Try putting this in the problematic VC:

 override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.navigationController?.setNavigationBarHidden(false, animated: false)
    }

And make sure the segues are using push. :)
