I have custom UIView, that uses .xib file. I'm adding this view in storyboard inside view controller. After that I added TapGestureRecognizer to it. Then I attach segue to tap gesture recognizer (no code needed to perform segue from custom view this way).
Problem is, navigation Item is not shown in interface builder. When I build and run app, navigation is on screen and everything works like expected.
When I add segue from VC to VC, navigation bar is shown in interface builder. Why I'm getting such behavior?
That seems like a bug in Interface Builder to me.
I see two possible workarounds for this situation:
Wire the segue from ViewController to ViewController. Give it an identifier. Call it programmatically with performSegue(withIdentifier:sender:) in an #IBAction for your Tap Gesture Recognizer. The downside of this is that you need to add code.
Add the Navigation Bar to your ViewController by setting Attributes Inspector -> Simulated Metrics -> Top Bar to Translucent Navigation Bar. This allows you to see the Navigation Bar in Interface Builder. The downside of this is that you need to do this for every ViewController down the chain.

Lets say we have a UIViewController embedded in a UINavigationController, the UIViewController segue to another UIViewController.
The second UIViewController has the standard left navigation button that "unwinds" to the previous UIViewController.
I don't seem to be able to add a righthand button (using a UIBarButtonItem) to the navigation bar of the second UIViewController via the Storyboard, when I attempt this the button ends up creating a tab bar at the bottom of the UIViewController (see below, notice also the left buttons are missing). Is there some trick I am missing?
I could embedded the second UIViewController in its own UINavigationController but then I loss the back button functionality.
I know it is possible to add the button in code so all is not lost if I am attempting something that isint possible.
To do this in the Storyboard, you need to place a UINavigationItem onto your UIViewController. Then you can add your UIBarButtonItem(s).
I have a UINavigationController in Interface Builder in a storyboard. I've added two UIBarButtonItems to the first UIViewController. They display just fine. How can I add them to the second UIViewController which is navigatated to? On that view controller, I only see the Back button.
When I try dragging a UIBarButtonItem to the top of the second view controller, the button ends up at the bottom of the scene for some reason. It is not displayed when running the app.
Edit: I should have mentioned that I know how to do this in code, but not in Interface Builder.
To add further informations about my comments concerning navigation item :
Here is a simple project with a UIViewController embedded in a UINavigationController. A second UIViewControllercan be pushed via the Next button.
If you select the next button, you can see in the hierarchy that this button is embedded within the group Right Bar Buttons Items, which is embedded within the First object. In fact, First is a UINavigationItem automatically added to your view controller when it was embedded in the navigation controller.
But the second view controller (the pushed one) doesn't have this navigation item since it isn't directly embedded within a navigation controller. Simply drag and drop it from the Object Library to your view controller.
#Slack, As i said earlier just drag and drop 2 "bar button item" in your navigation bar.
I have added to my tableView with navigationController a bar button with text "Start!".
But I can not see it anymore in the storyboard.
In my build I can see it:
I think this is also the reason for this error log message:
pushViewController:animated: called on while an existing transition or presentation is occurring; the navigation stack will not be updated.
What can I do to make the bar button visible again?
The tableviewcontroller is covering the navbar in your storyboard. Check the properties in the storyboard and verify that your tableviewcontroller is inheriting his geometry. (setting is called inferred)
My app has two scenes: a UIViewController with a navigation bar at the top, and a UITableViewController. If I wire up a button in the first scene to segue to the table view, everything looks great. However, if I wire up a tap gesture in the first scene to segue to the table view, then the navigation bar doesn't display in the second scene in Xcode. When the app is run, the navigation bar appears as it should, but in the storyboard editor it is gone.
Is there something special that needs to be done to preserve the navigation bar when segueing from one scene to another using a tap gesture? To implement the tap gesture, I dragged it onto one of the elements in my storyboard, then control dragged from the "tap gesture recognizer" icon at the bottom of the scene to the scene I wanted it to segue to. Then selected "push" for the segue type.
I never noticed this before, but I do see the same thing. This seems like a bug to me, but maybe Apple has a reason for doing this. You can go to the "Simulated Metrics" for your controller, and set the "Top Bar" to be a navigation bar, which will allow you to set the title and add a bar button item if you want.
I am completely new to ios development and I am only interested in developing for ios5.
I have an app with some scenes, they are mostly tableviews. I also use a navigation controller
I however need to add some status text and buttons that are always visible in all scenes and thought that a toolbar added to the navigation controller should do the trick.
so i thought that i should only have to drag out a toolbar in storyboard to the navigation controller, but it does not stick there. I can add it to the bar underneath with first responder and navigation controller but that does not help me (small icons).
I can also not add it to my table view (but if i drag out a plain view I can add it there)
do I have to make my own custom navigation class that the navigate view uses and then programatically add my toolbar?
Had the same question recently. Check Attributes Inspector in your ViewController's properties in storyboard. There you can define a Bottom Bar.
Well, inside the UINavigationController, you should have something... A UIViewController for instance. You can easily add a UIToolBar by dragging the object inside the UIView of the UIViewController. What might being happening is that as the root view you have the UITableView, in that case I think you can't do that. But to better understand, just take a small print screen of your StoryBoard.
If you zoom up to 100% on the storyboard it should drag.
