I'm using custom segues with no animation because I don't like the animation of the default segue. The problem is that in the storyboard, when I flip the segue style from Push to Custom, the view controller's navigation item disappears. Now, it seems that the navigation item still works even if the segue is set to Custom, but that means constantly flipping back and forth between Push and Custom when changes need to be made.
Is there any way to use a custom segue and still have IB access to the navigation item?
Yes, select the view controller and open the attributes inspector. Then change the "Top Bar" from "Inferred" to "Navigation Bar". That should keep the navigation bar displayed.

When using a segue from a slide out menu to other view controllers, my toolbar and navigation bar both disappear. I fixed the navigation bar disappearing by segueing to a navigation controller, which then set the desired view controller as the root of the navigation controller. However this does not fix the toolbar issue. Should this not have fixed the toolbar disappearing as well? Either way, what is the best solution to my issue?
Thanks!
I have had this problem using SWRevealViewControllerLibrary. In your storyboard make sure you are using "Reveal View Controller Push Controller" segue. If you have multiple segues, when you click on them you may find some things like the toolbar disappearing from the storyboard. If so then simply make a new one in the storyboard.
As for the second part of the question, from what I can tell toolbars are not by default part of a navigation controller's 'root' view, and so may change across controllers - just like how if you created a button or label in your first view, they would also change.
In the current version of Xcode a few things seems to work a bit different.
I have a little problem working with a simple navigation. This is what I do:
I have a Storyboard with two scenes.
I connect the scenes with a segue of type "Show".
(In the past I did use "Push" but that is deprecated now.)
I select the first scene and choose "Embed in Navigation Controller.
Now both scenes will get a gray bar at the top but only the first scene will also get a Navigation Item.
Only for the first scene I am able to edit a title attribute and only for the first scene I am able to add a Bar Button.
Navigation itself works fine. The title of the first scene is the text of the Back-button in the second scene.
Why has the second scene no Navigation Item?
Is it because of the segue type?
Yeah, its a bug in Xcode from version 6. If you want Navigation Item in second view controller too, then there is a hack to get it.
Change the seque type from show to push. Now Navigation Item will appear in second VC too. You can again change the seque type from push to show, the Navigation Item will still present in second VC.
IB will automatically add UINavigationItem to root view controller of your UINavigationController.
To the rest of your controllers in navigation flow you need to add UINavigationItem manually from IB Object library.
What I do is to drag a navigation item from the list of controls to the top, gray bar on the second ViewController. Then you can drag other items such as bar buttons onto it, as well as being able to edit the title.
There are 2 View Controllers in my storyboard, VC_A and VC_B
I have embeded a navigation controller in VC_A which is a Table View Controller, I then control drag the Prototype Cell into VC_B to create a segue. If I select "show" in "selection segue" then in VC_B I can see the outline of the navigation bar but I am unable to select it or add any bar buttons to it, it also doesn't appear in the hierarchical view.
However if I select the "push (deprecated)" option when choosing the type of segue, I am able to select the navigation bar in VC_B and add buttons to it, it also show up in the hierarchical view as a Navigation Item.
The only work around I can find is to choose show, then change the segue to push(deprecated) in the Attribute Inspector so the Navigation Item will show up in the hierarchical view, then change the segue back to show. But I am worry that this might cause problems further down the line.
Is there a way to add a Bar Button to VC_B's navigation bar without using the work around?
Just drag the "Navigation Item" from object library to the navigation bar and it should work as expected. You can make changes as you like and it works exactly like in Xcode 5.
Interestingly, when you first time made the connection b/w your table view controller and view controller using Push you can start editing the navigation bar without a problem (e.g put bar items onto it).
Then delete the connection between your table view controller and view controller (but do not delete the nav bar items you just added), then re-connect the two controllers by using segue Show, you will see the navigation bar works just like segue Push now.
Hope it helps
I think the way you do it (going through the deprecated push) is not wrong even though there's another way. In fact, when you turn the Segue into a push, you get a Navigation Item out of it.
So all you have to do is add a Navigation Item to your View Controller and that'll do the trick:
This seems Xcode bugs.
In my case, i am re-create segue by this sequence:
Delete existing seque. (I am using "Action segue - Show")
Drag new segue with "Non-Adaptive Action Segue - Push (deprecated)"
Delete segue no.2
Re-create/connect "Action Seque - Show". (No.1)
Done
Now, i can edit navigation title and add custom navigation item button as usually.
I am using Xcode 6.4, and minimal target iOS version 7.
In your viewController :
self.navigationItem.title = "Second VC"
self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Play, target: self, action: "playFunction:")
I have set up a view controller in Storyboard which is embedded in a navigation controller. In this nav controller I have checked Shows Navigation Bar and Shows Toolbar and enabled a navigation bar and toolbar in Top Bar and Bottom Bar respectively in Simulated Metrics. I then "Show e.g. Push" segue from the view controller to another view controller. On both view controllers I've set up Simulated Metrics the same way, so both the navigation bar and toolbar are visible on all three controllers.
The problem is, I can add bar button items to the first view controller to both the navigation bar and the toolbar, but I cannot add a bar button item to the navigation bar on the second view controller. When I drop a button on the navigation bar, it's added to the toolbar instead. And I cannot double click the nav bar to add a title. In the outline I see there is no navigation item on the second view controller, but it is there in the first view controller.
I can probably add buttons to the navigation bar programmatically, but I want to do this visually in Storyboard. My question is, what is wrong with this setup, or is this a bug with Xcode?
For XCode 6, the UINavigationItem for the 2nd view controller onwards is not added automatically on the View Controller Object inside the storyboard. You will have to drag the UINavigationItem onto the Navigation Bar for that view Controller Object before adding UIBarButtonItem on top of it.
I am not sure why it is designed that way. I only discovered about this a few weeks ago.
If you have a ton of view controllers and very little custom auto-layout stuff in place, you can disable size classes, then re-enable it will add all missing nav bars across your storyboard.
Obviously not recommended if you have a ton of custom auto layout stuff linked up.
If you have just a single UIViewController that's missing a nav bar, just drop a UINavigationItem onto it.
If you're using Xcode 7 beta 4/5, try restarting Xcode it solved the issue for me
I just bumped into this issue and it seems to be affected by the segue that shows the view controller.
If "Kind" setting in segue is "Show (e.g. Push)", it's not possible to drag the item to top right corner. However, if you explicitly change "Kind" setting to "Push", this can be done.
Edit: actually I just noticed that "Push" is deprecated. Not sure what Apple is thinking here. However, you can just change it back to "Show" after adding the button and it seems to work :D
For second view controller in hierarchy, you can setup title in attributes, without adding "navigation item"
I think it is a bug. I had the same problem.I fixed this problem by disable the size classes, then enable it.
You can disable and enable the size classes in Interface builder doc.
It's very simple. You just need to use navigaitonItem first as the holder of the buttons and then you can add barButtonItems on top of that.
I have a UINavigationController and when I push one of my views, I have a UINavigationBar on top that I made an ivar for and connected it. Now what I need is that button that is like half square and half arrow on the left of the bar. How would I do this programmatically? All I need it to do is say back and do my back action when it is clicked. How would I do this?
Thanks!
If you're using a UINaviationController, then each view controller that you push onto it does not need it's own UINavigationBar object set up in the nib or in code. You get it and a back button 'for free' when you push a view controller onto a navigation controller's stack.
So remove the UINavigationBar from your pushed view controller. It could actually be blocking the navigation controller's navigation bar.
If you're using a nib to set up your view controller, you can add a 'simulated element' so that you have a fake navigation bar in the nib to help lay out your UI elements.
EDIT: in Xcode 4, they're now called 'Simulated Metrics'. Set the 'Top Bar' to simulate a navigation bar in your nib.
