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've got 3 view controllers. Two I have hooked up to a tab bar controller and one that I'm wanting to access when a user selects a cell on the second view controller in my tabbed views.
I'm wanting when the user hits "back" on the 3rd "detail" page for the user to be taken back to the 2nd view.
When I do this by just adding a button and segueing back to the 2nd VC, the tab bar is gone. I tried in my viewDidAppear to unhide the tab bar, but I guess going off of the tab bar controller messes up the navigation.
I tried creating a variable that was like "didHitBack" and on my "back" button on the 3rd view I'm creating a segue back to the Tab Bar Controller, and if "didHitBack" is true I do
_ self.tabBarController?.selectedIndex = 1
which takes me to the second page, but it's loading the first view in then going to the second page which looks bad.
I was thinking maybe there was a way to do "didHitBack" and setting the tab bar's initial view controller to the second one or something, but that all just seems very wrong.
Is there a "proper" way to do this?
To recap I have VC1 and VC2 that are hooked up to a Tab Bar Controller, I have a tableview on VC2 that on didSelectRow I'm going to VC3 which I do not want to be a part of the tabbed view controller, and when I hit back on VC3 I want to go back to VC2.
If you want to build a navigation stack, you should embed your view controller in a UINavigationController
So your tab bar would be hooked up to VC1 and NavVC. The root view controller of NavVC would be VC2.
You can then push a new view controller onto the stack using the navigation controller (or pop the view controller to go back) all within the confines of the tabBar.
My second view controller is a table view controller. I wish to segue to a first view controller with a back button. I have tried using Editor>Embed In>Navigation Controller. It places a navigation bar on the top where I can place an Item (Back button) on it, and after segueing it back to my first view controller, it becomes very screwy (it shows two navigation bars on top of each other). Is there a better/easier way to move back to my first view controller?
if u want to use navigation controller to manage ur push&pop stuff, just make sure:
navigation controller is ur initial view controller
ur first view controller is the root view controller of navigation controller
set an unique identifier to second view controller
leave ur second view controller alone without any link to other vc
like this
then push like this
let secondVC = (self.storyboard?.instantiateViewControllerWithIdentifier("identifier"))! as! urVC
secondVC.title = "second view controller"
self.navigationController?.pushViewController(secondVC, animated: true)
and pop like this
self.navigationController?.popViewControllerAnimated(true)
alternatively, u can use unwind segue following this tutorial
I have three view controllers in my storyboard.
In second controller I have navigation controller embeded. Second controller is connected to third with segue.
From first view controller, I call second one by presentViewController. In presented view controller I press a button that trigger a segue. What I expect is to see navigation controller in second and third view controller, but third viewcontroller is also shows from bottom to top with out navigation controller.
How to make nav controller visible in second and third view controller ?
Select the segue
between your secondView and thirdView in your StoryBoard
and look it has this settings:
Take care the identifier is what you want, the key here is the kind type of segue
I have to view controller, One has a button and the other is embed in a navigation controller. I Don't know how to make a proper segue to that second view controller including a back (unwind) segue. That is in swift.
You're going to use a navigation controller. Go and select your view in the storyboard, and select Editor -> Embed In -> Navigation Controller. Do the same for the second view. Now, add a button in the first view that connect to the second view on a click. Make sure when you drag and drop that it's a push segue.
Voila! You should now have your navigation controller working.
I have a storyboard setup as a Tabbed Application with first view controller containing a
UITableView. The Protoype cell has a "push" segue to detail view which is embedded in a navigation controller. So far so good. The detail view pushes when a cell is selected and there is a navigation bar item to get back to the table view.
Now I run into trouble. The detail view has 2 buttons "Map" and "Ticket". If I create a new UIViewController, embed it in a navigation controller, and ctril-drag a 'push' segue from a button to the new view controller as before, the app crashes instantly with a SIGABRT when I click the button. If I don't embed in nav controller and use a 'modal' segue instead it doesn't crash but it seems a natural flow to continue with the 'horizontal slide' animation and the nav bar button back to the detail view.
Once I can stop that crashing I would like to connect the other button to it's own view controller with a UIMapView.
What am I doing wrong?
You don't need to embed a navigation controller in the detail view. You only need one at the top level. Take out the navigation controller in the detail view controller and just do a push from there to the next view.
