Toolbar disappears after segue - Swift - ios

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.

Navigation Item in XIB file is not visible

I'm in XCode 7.2.1 and I am trying to make a view that is reusable and should have some custom elements in the navigation bar.
If I would add a view to my storyboard, connect it via a segue to the navigation controller and make sure there is a "Navigation Item" in the view, I could see the navigation bar and edit my items in it.
If I manually add a Navigation Item to a XIB however I can't see anything. Even if I switch in the simulated metrics settings Top Bar to something else than Inferred or None.
I don't want to use the storyboard, if possible. Is there a descent way to make the navigation item visible and edit it?
Thanks in advance.
I don't think you link your View Controller correctly with Navigation Controller. When you link it, you should choose with root View Controller. If you link it correctly, you don't have to add NavigationItem manually.
By the way, you shouldn't do the customization for Navigation bar directly in xib. All you can do is only to set the Title, Prompt and Back Button text.
Do it in code! I think you won't have different styles for navigation bar in different views, right? That would be too silly.

How to add buttons to navigation controller visible after segueing?

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.

Using UITableViewController in a navigation bar

I'm new to iOS, but I know the basis. I want to host 3 UITableViewController in a UITabBarController using the storyboard.
I dragged a UITableViewController from the object list(?) and control dragged creating a seguel. Now the tab shows successfully the table view controller.
The issue is the rows are taking the space of the status bar. So I want a navigation bar(?) there, with a title. Since I'm new to iOS I don't know the following:
Given the fact that UITabBarController is the first controller ever, the hosted UITableViewController should not have a back button, obviously. So is it correct to use a navigation bar to display a title (and possible add/edit buttons)
If so, I tried dragging the Navigation Bar but it doesn't work.
What am I missing or doing wrong?
hope this helps
actually it is done for another answer. but it will be handy to u too
You will want to add in 3 UINavigationControllers. Have each tab in the tab bar controller segue to a different navigation controller. Then set the root view controller for each navigation controller to one of the table view controllers.

Custom segue causes navigation item to disappear

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.

Modal Segue Into Navigation Controller with No Nav Bar

In my storyboard I have a view with a segue into a new view that's embedded into a Navigation Controller (so the segue points to the navigation controller). I have the segue set to a Modal transition, however when the new view is animating up, it contains the standard blue navigation bar above the view (which then animates out of view).
Here's what it looks like mid segue: http://i.imgur.com/3eqAQ.png
How do I make it so the modal view animates up but without the navigation bar?
I have tried hiding the navigation bar in the embedded view's init, viewWillAppear, and vieWillLoad methods and that doesn't work.
I event went so far as to create a custom subclass of UINavigationController and set the navigation controller in the storyboard to it.
Thanks!
This may sound pretty simple, but have you tried hiding the navigation bar immediately before the modal segue starts? I had this problem when presenting a modal view controller and adding a [self.navigationController setNavigationBarHidden:YES] immediately before the presentation did the trick for me.
I had almost the same problem, but I wanted to get a navigation bar for my modal transition, as it was always hidden.
There may be two ways for you to remove the navigation bar:
Make sure that your view controller is not embed in a navigation controller, as it would put one by default
Check the "Top Bar" attribute of your previous controller in the workflow and work with none/inferred values depending on your storyboard.
