I have a problem with SWRevealViewController. In my app I have a long chain of UIViewControllers connected to a single UINavigationController. After adding a side menu and setting the "reveal view controller push controller" segue for cells I see only ViewControllers connected with a segue. I can't move between my UIViewControllers in the chain any more. And navigation bar is missing. Is it possible to use a side bar and UINavigationBar at the same time?
I see your image I think you have to add another navigation controller before the C****** S****** View Controller or the view controller you want to go
the reason is that there is no UINavigationController before the C****** S****** View Controller and that's why Navigation bar is hidden and you can't move

Back when I first created the foundational layout for the app I'm currently working on in Storyboard, I did it in two steps:
Selected my View Controller and used Editor->Embed In->Navigation Controller.
Selected my View Controller again and used Editor->Embed In->Tab Bar Controller.
This was the resulting layout:
Question 1: Why do these steps create such an odd layout?
In this weird layout that seems to imply that the Navigation Controller is attached to the Tab Bar Controller as its parent, the only way I can get navigation items to display in the app (in the view controlled by the View Controller on the right) is by placing them in the nav bar of the Tab Bar Controller scene.
However, this creates various issues, including not being able to create an IBOutlet in my View Controller file for a custom view I drag into the title view slot in the Tab Bar Controller scene. Meanwhile, dragging anything into the navigation bar in the View Controller scene just makes it not appear in the app when it runs.
Question 2: How can I fix this layout so that I can control-drag from navigation items into my View Controller file? Or is everything actually correct, and I'm just trying to force something I shouldn't? (My intention here is to be able to set the custom title view's text in my View Controller code.)
Its obvious, if you want to embed MyViewController to NavigationController then you need to change your second step and need to embed NavigationController to Tab Bar Controller.
Selected MyViewController and used Editor->Embed In->Navigation Controller.
Selected NavigationController Embed with MyViewController and used Editor->Embed In->Tab Bar Controller.
It should look like this.
Note: You need to embed MyViewController to navigationController only if you want to perform push operation on this TabBarItem means with MyViewController other wise simply embed MyViewController to TabBarController no need to embed it with NavigationController.
I'm trying to display the navigation bar at the top of the screen, but it's not showing in embed navigation controller.
Here is how it is in the storyboard:
And here it's in the simulator:
As you can see, I created a custom TabBar (following this tutorial) at the bottom of the screen so I can navigate between the different views.
I believe that I'm going to have to load the navbar programatically because the only solution that I found was to set the navigation controller as the initial view controller, but I already set another view as the initial one so I can't do that.
Issue :
When you instantiate a viewController using storyBoard identifier they wont come with free embedded navigation controller, even if you have added a NavigationController to them. As a result you are adding a viewController without navigation bar to your tab bar VC.
Solutions:
Solution1: If you want each child viewControllers to carry their own navigation controller hence their own navigation stack, provide a storyboard identifier to Navigation Controller behind your child viewControllers and instantiate the Navigation controller itself rather than ViewController. And add NavigationController as you tab bar looking VC's child. Because navigation controller loads the embdedded VC by default you will see your child VC with nav bar.
Solution2: All that you care for is only nav bar than add the Navigation Controller behind the VC containing tab bar looking View.
Hope it helps
Have you tried constraining the navigation bar to your view? Otherwise it can move offscreen.
You need to point the tab bar controller segue to the navigation controller of your view - otherwise if you point the segue straight to the view you're just loading the view without any navigation controller attached.
The Problem
I'm relatively new to Swift and I'm trying to build an application that makes use of a UITabBarController.
What I'm trying to do is put a different navigation bar (or UINavigationItem) on each of the tabs in the UITabBarController.
For example, I want the UINavigationItem I set, with its bar button items, to appear on MyViewController instead of a back button to the previous view controller, such as shown on the image below.
The current layout on the Storyboard is as follows.
MyViewController on the sidebar:
What I've Tried
Someone suggested that I should embed each UIViewController (e.g. MyViewController) in a Navigation Controller. I've tried this and it doesn't work.
I've also tried to set the Top Bar to "None" in the Attributes tab of the options menu.
Thank you in advance for your help.
Here is how i did it,
UINavigationController -> UITabbarController
And then each "Tab" is in different Storyboard and every storyboard start with a "Navigation Controller". So yes every tab in different navigation controller this how you should do it.
Different storyboards because may be multiple people work on storyboard at same time.
Why TabbarController inside Navigationcontroller ?
I put the "TabbarController" inside "NavigationController" because some of the controllers i want them to be full screen, like hiding the "Tabbar" so for that i push them from main NavigationController.
//Out of context but may help you,
I have created an "Extension" of Navigation Controller to push a view controller on main navigation so that any of the tabbars (which are also inside navigation controllers) can easily use the extension to push any view controller if want to hide the tabbar.
Let's assume that a first view controller is connected with a UITabBarController and I want to make a push segue to the second view controller from this first view controller.
From my googling, it seems that a modal segue from a view controller connected with a UITabBarController hides the bottom tab bar, while a push segue doesn't.
However, my push segue is also hiding my tab bar in the second view controller. I have overridden prepareForSegue method in the first view controller.
Below are images of my storybard and the simulator. Anyone has an idea why this is the case? Thank you in advance for your helps.
Your trouble is because your tabViewController is embedded in the navigation stack that you initialise with your login screen.
you need to rearrange things so that each of your tab bar controller tabs opens to a new navigation stack.
What I suggest
your loginscreen should navigate to your tab bar controller with a modal/presenting segue, not a push segue. Remove the navController that encloses the loginscreen, you don't need it (well, even if you keep it, don't use a push segue, use a modal segue, and you won't then be referring back to that navController's viewController stack from inside your tab bar).
embed each of the first viewControllers in your tabViewCOntroller inside a separate navController.
Now you can push segue within your tabViewController's tabs.
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.
