In the picture below (We'll call them storyboard item A, B, C in order from left to right), View controller 'C' does not show a back button but I embedded it in a Navigation Controller. Other Stack overflow posts have not worked. How do I get the back button to show?
Move the Navigation Controller to the "first" view controller (ie: the view controller that does the "pushing" or "showing"). The Navigation Controller should not be embedded in the view controller that contains the back button but rather in the view controller upstream of it. This is the main cause of confusion.

I'm making an application that has:
Navigation Controller -> View Controller -> Navigation Controller -> View Controller -> Navigation Controller -> View Controller.
This is making it so that there's no back button on the second view controller, only the third one, and I can't get it to appear. I'm fairly new to iOS and simply want to have a path of view controllers that the user can navigate down and back. Is there a way to add the back button to the second view controller's nav bar? Is there a better way to do this? Is it problematic to just create buttons at the top of views that perform segues?
I found some Objective-C solutions but couldn't find anything in Swift. Thanks for your help!
Remove all the navigation controllers except the first one.Your app must be like this..
Navigation Controller -> View Controller -> View Controller -> View
Controller.
Call segue to move to the other controller .. Just dismiss your controller if you have modally showed them on back button pressed or pop them from
navigationController
if you have pushed them.
Now for Back, you can do it in multiple ways. One of them is, add a view on the top of your controller, add a button on it and implement an action when someone taped it..
I hope you will got that ...
I have the following on my storyboard:
A navigation controller with a table view controller as its root view controller.
The table view controller's navigation item has right bar button (Add) that segues to a 2nd navigation controller.
The 2nd navigation controller has a 2nd table view controller as its root view controller.
The 2nd table view controller's navigation item has a left bar button (Cancel) and a right bar button (Save) both of which unwind back to the 1rst table view controller.
This all works fine: I can navigate from the 1st table view controller to the 2nd and back.
If I remove the 2nd navigation controller and instead segue directly from the 1st table view controller to the 2nd then the 2nd table view controller's navigation item is not displayed. What is going on? Why do I need the 2nd navigation controller?
remove the intermediate navigation controller and connect your second VC to initial vc and change your segue type kind model from present modally to show e.g push
if you are using present then navigation controller is not a manodatry but on your save and cancel button purpose you need to embed with navigation controller, in here you push then no need of Second Navigation Controller.
on navigation use
[self performSegueWithIdentifier: #"sample" sender: self];
on your second by default navigation bar will comes, if you need add barbuttons in right and left side, once press the done button use the following comment
[self.navigationController popToRootViewControllerAnimated:YES];
it automatically come back to initial VC,
you can get the detail of segues in apple
You don't need a second navigation controller. This is what you need to do to after you do a Show segue to the second TableViewController:
Confirm that you're actually doing a Show (e.g., Push) segue. If you have to do a Present Modally segue, then you will need another UINavigationController.
Add a Navigation Item (not a Navigation BAR) to the second TableViewController. You'll then be able to add a title, add navigation buttons, etc.
I have a View Controller (A) with a text field and some other things in it.
When the user presses a button on View Controller A it segues to View Controller B using "Present Modally".
How could I preserve the state of View Controller A (e.g. text in the textfield) when returning to it from View Controller B. I would rather avoid using NSUserDefaults if possible.
Thanks!
When you present view controller B modally on top of view view controller A, view controller A is not closed - it's just covered by view controller B. The close action on view controller B should invoke dismiss(animated:completion:) to dismiss the modal. When you do that you can be certain that view controller A will be revealed with its state intact.
You should NOT use a segue to go back to view controller A. That would create a new copy of view controller A that would wind up being displayed on top of the original view controller A and the new view controller B. That is a bad idea.
This is my story board:
Whenever I jump to a view controller embedded in navigation controller, the navigation bar is shown but empty, why?
The sequence I created it is:
connect buttons with destination view controllers
embed destination view controllers in navigation view controller
And the segue I use is present modally - cross dissolve.
The First root controllers of a navigation controller won't have any Back button attached to its navigation bar. You should add an additional View Controller next to any root View Controller of Navigation Controller with Push Segue ( or Show Segue for newer IOS ) to navigate between them.
I tested different segue transition methods with test projects, the answer I got is: if you are transitioning by presenting it modally, you don't get the back button, you only get it by push.
I have a master detail class that has a navigation view controller. I have created another view controller which I want to use to load the navigation view controller via a button. I have added a view controller and have linked a button to the navigation view controller however when i test to see if the new view loads, I receive an error on the main.m
What am i doing wrong?
I think you need not take another navigation controller if you have navigation controller for the view controller having button and you can directly take view controller which you want (UITableviewController or UIViewController). Give connection from your button to that view controller
