Why is adding a navigation controller making my array disappear?

Question

Currently I have a UIViewController with a couple of buttons that when pressed move to a UITableViewController. Each button loads a specific array of data to the UITableViewController by identifying the segue of the specific button and displaying the corresponding data. This works fine as is.

However I wish to add an embedded UINavigationController so I can navigate through the UITableViewController and and corresponding views while still being able to 'press back' to the initial UIViewController.

Firstly, where am I meant to put this. I tried over the tableViewController and 2 things happen -

a) If the segues still go to the UITableViewController, there is no navigation displayed.

b) If I move the segues to go to the UINavigationController, none of my arrays show in the tableViewController, but I do have navigation.

Where do I link my segues or where do I embed the UINavigationController so this works? (I haven't put any code as I don't think this will involve it, but if it does just let me know and I will add).

Not sure if I'm missing something but, it's not working. I want to be able to still utilize the buttons I already have and not use the buttons on the navigation from the UIViewController to the UITableViewController.

For Hiding the Navigation on root

- (void)viewWillAppear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:YES animated:animated];
[super viewWillAppear:animated];
}


- (void)viewWillDisappear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:NO animated:animated];
[super viewWillDisappear:animated];
 } 

Answer 1

The ViewController which has 2 buttons can be made as rootViewController to the NavigationController. The NavigationController can be added to the window.

Window -> NavigationController -> UIViewController (as rootView)

Hope this helps.

Answer 2

Select the root view controller->editor->embed in->navigation controller
