Use Storyboard References While Retaining Icons & Text for Tab Bar Controller - ios

I started refactoring one of my projects to make the code easier to manage and the Tab Bar Controller lost its icons for which tab represents what. Without this I'm a bit lost which tab is what for re-ordering purposes.
How do I get the icons to show up again for a tab bar controller when I'm using storyboard references?
Refer to my attached image. Notice how the first 3 tabs are 'blank' but the other tabs that I have not refactored yet show with the icons and titles.
For those unfamiliar with storyboard references I was following the tutorial here: http://code.tutsplus.com/tutorials/ios-9-staying-organized-with-storyboard-references--cms-24226
Sample of Tasks Storyboard to show Icon set Correctly

It seems another solution that worked for me without altering the Approach you went through:
Leave Storyboard references as it's
Go to Initial view controller in the referenced storyboard
Add Tab bar item to the scene
Configure it as you have done in UITabBarController storyboard
Clean & Run
Repeat it for all Storyboard references
Happy Coding!

First, in the storyboard where the tab bar controller is, there should be a scene for the referenced storyboard.
Just click on the scene that tab is associated with and click the tab bar at the bottom, then go to the attributes inspector, and you'll be able to assign a new icon to it.

Update - This approach no longer appears to work in Xcode 9.
Here's how to get the tab to show properly:
Put the first UIViewController that will be embedded in the tab in
the same storyboard as the UITabViewController.
Ctrl + Drag from the tab bar controller to the content view
controller to make the connection as per usual. This will
automatically add the UITabBarItem to the bottom of the content view
controller.
Select the content view controller.
Click the Editor menu and choose Refactor to Storyboard...
The UITabBarController tab will now point to the new storyboard
reference...
... and the content view controller preserves the UITabBarItem from
the tab bar relationship. It will appear normally in the app now.

For some weird reason, I wasn't able to see the tab bar in my reference view controller in IB. Although while selecting it and expanding the Document Outline, I was able to see it in my view list. I could make my changes through it.
Hope this helps! :)

XCode 11.1: The following approach gets the desired tab title and icon to show at runtime:
Create a storyboard reference to the desired storyboard (including the correct bundle identifier if it is located in an external framework).
Ctrl-drag from the tab bar controller to the reference you just created and select "Relationship Segue > view controllers" from the context menu that appears.
The tab bar should now show a square image with the title "Item" beside it. Click and drag this item to rearrange it in the bar as desired.
In the target view controller (which should be the first responder in the referenced storyboard), create a Tab Bar Item and set the Title and Image properties in the Bar Item section of the properties panel.
At this point, the correct title should appear at runtime (but not at compile time in the storyboard editor). If the icon is there too, great. If it's not, you can try checking that the image reference is valid and located in the same module as the tab bar item (i.e. in the same framework). If it still doesn't appear, here's a hackish workaround that will work:
Create a new class which inherits from UITabBarController.
Override viewWillLayoutSubviews as follows:
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
// Set the tab bar image at runtime
if let exampleTab = tabBar.items?.first(where: { $0.title == "ExampleTitle" }) {
// To insert an image literal, type "Image" and select Image Literal
// from the autocomplete menu. An icon should appear.
// Double-click the icon and select the desired image from the grid.
exampleTab.image = Image Literal
}
}
Change the type of your tab bar controller to the subclass you created (from the Identity panel in the storyboard editor).
Finally, the tab bar item should now appear correctly at runtime. If anyone knows how to make it appear correctly at compile time too (in the storyboard editor) for a storyboard in an external framework, let me know.

If you embed a navigation controller before your scene, you then can edit it like normal.
Select your storyboard reference then:
Go to the top and click Editor > Embed > Navigation Controller

show another storyboard as the content of 1st tab of TabBarController

I have a tab bar controller in storyboard like below:
I have anther storyboard which I would like to use as the content of 1st tab. Let's call it Content.storyboard
What I want to achieve is:
I would like the content of the 1st tab of Tab Bar Controller to be the Content.storyboard.
What I tried is:
I removed the default 1st view controller from Tab Bar Controller storyboard and added a storyboard reference connecting from Tab Bar Controller to Content.storyboard, like below:
The problem is , as you see above, I lost the ability to edit the Tab Item.
So, what is the correct way to achieve what I want? (That's showing a view from another storyboard as content of a tab of TabBarController)
I ran into an issue similar to this recently. I ended up moving the navigation controller out of the separate storyboard and into the main storyboard and configured the tab bar items there.
EDIT
After some further testing, it looks like the storyboard reference node gets a fake tab bar item. You can't delete it or modify it.
To provide the tab bar item for the other view controller, go into that storyboard and set the view controllers simulated metrics to Translucent tab bar:
Then you can drag in a tab bar item from the object library:
I chose the Bookmarks system icon. you won't see this reflected in the main storyboard, but you will at runtime (and on the child storyboard).
You can achieve this using container view
1) Take Container view in your tab
2) Delete added viewcontroller window (Usually come with container view )
3) Add storyboard Reference
4) Drag from container view to storyboard Reference choose embed option
I have also faced the same issue:
Follow the step:
Go to your Content.storyboard
Expand your initial view controller.

After that:

Nothing shown at tab bar controller items when storyboard reference is added

I have a tab bar controller and there are some view controllers attached to it. All of the view controller names and their corresponding items show up perfectly at the tab bar. The problem occurs when I try to add a Storyboard reference to it. Nothing is shown at the tab bar for that particular item(storyboard) when I run it. Although it shows up perfectly on the UI design.
[
Notice that the 3rd item (the storyboard reference) is invisible. Also, the invisible Storyboard reference works. Meaning, if I click on the invisible place it takes me to the proper storyboard.
I have seen some answers from here.
Refactoring to storyboard works. But I don't want to use it. Refactoring to storyboard creates a storyboard reference anyway. And it works perfectly. But when I create a storyboard reference, it doesn't work and stays blank.
Now, how should I add a storyboard reference to tab bar controller so that it shows up the name and the icon?
After the storyboard reference is correctly connected but the icon image doesn't appear, go to the initial view controller that is in the storyboard being referenced from the tab bar and make sure that the view of the initial view controller has a Tab Bar Item.
If it does, then add the desired image to the Tab Bar Item connected to the view. If the connected storyboard view does not have a Tab Bar Item, then add one and set the desired title and image. For other potential fixes this post is pretty good.

Tab bar icon and title not showing with Storyboard References

I have the following storyboard with a segue to a storyboard reference:
The problem is that when I run the app, it doesn't show the icon or the title:
These are the item settings:
What am I missing?
Here's how to get the tab to show properly:
Put the first UIViewController that will be embedded in the tab in
the same storyboard as the UITabViewController.
Ctrl + Drag from the tab bar controller to the content view
controller to make the connection as per usual. This will
automatically add the UITabBarItem to the bottom of the content view
controller.
Select the content view controller.
Click the Editor menu and choose Refactor to Storyboard...
The UITabBarController tab will now point to the new storyboard reference...
... and the content view controller preserves the UITabBarItem from the tab bar relationship. It will appear normally in the app now.
You can modify image/title of the tab bar item in the initial view controller of the storyboard you are referring to. You just need to add a 'tab bar item' to the initial view controller and change its properties (title/image) accordingly.
Outline view of the root view controller in the referred storyboard
The modified tab bar item in the view controller
Note: the change will not be reflected on the tab bar in the main storyboard; you only see it in the referred storyboard and at runtime.
The problem is that in the target view controller, you don't have a UITabBarItem in the views hierarchy. The TabBarItem is related to the storyboard reference, but should be related to the View Controller.
Looks like a "bug" in Xcode...
To resolve this you can do the following:
Just create the segues from the UITabBarController to the Storyboard references.
You may configure the Tab Bar Items in the storyboard references, they don't do much more other than showing the tabs in the tab bar on the Storyboard, which is nice for development purposes.
If you now run the app, you will indeed notice that the tabs are missing.
To get the tabs to display in the running app as well, do this:
Go to the viewcontroller the storyboard reference is referencing to
Add a Tab Bar Item into this View Controller by dragging it from the Object Library into the View Controller
You will now see a tab bar with one single tab in the view controller
Configure the tab bar item to show the correct title and icon
Now run the app and you will now see your tabs.
I tried adding another tab bar, then added tab bar item, selected and image for it BUT Non of above seemed to work with my case ..
it was like this :
Then i compared it with VC that were working properly with TabBar icons..
later i found that my navigation items and tab bar items were not together :
Now its working :):)
After struggling with this problem for a few days I found this solution.
Double click the storyboard link, which will open the referenced storyboard. In the scene navigator, you can edit the bar item with a custom title and icon. Works in xCode 9.
Storyboard
Scene Navigator
I had this exact same issue and neither of the above answers worked in my case. I solved by setting my tab bar image in the image bar item section inside the storyboard's reference like shown in the attached image:
I made following in the storyboard and made class for each UINavigationController
and made following code in each UINavigationController class
override func viewDidLoad() {
super.viewDidLoad()
let someController = StoryboardManager.surveyStoryboard.instantiateViewControllerWithIdentifier("SomeController") as! SomeController
viewControllers = [someController]
// Do any additional setup after loading the view.
}
I did it in different way. My fourth tab was not showing. I just programmatically placed image on its place. You need to set its X,Y coordinates accordingly.
let imageName = "video"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: view.frame.width - 80, y: view.frame.height-70, width: 50, height: 50)
view.addSubview(imageView)
Just add a Tab Bar Item in the "child" view controller:
this works for me

Adding new tabs to a tab bar controller

I am creating a tab bar iOS app. The tab bar view controller has two tabs, each of them connected to a view controller.
This how it looks:
I need to add more tabs to the tab controller. I am doing it at the storyboard as follows:
I add a new view controller.
I control-drag from the tab bar controller to the new created view controller.
A window opens and I select Relationship Segue-View Controller.
The segue from the tab bar controller to the new view controller is created.
I think that is the way to do it, but after that the tab bar controller doesn't show any tab icons, the tab bar becomes grey.
Like this:
I need to know what am I doing wrong.
First drag A TabBarController from Object Library you see that only two tabs with thier VC there.
to add more Tab Item in TabBarVC drag VC from Object Library
Then Control drag from TabBarVC to Newly VC then Segue relation pop ups
Select last one Relationship Segue -> View Controllers
I had the same problem until I added a tab bar item from the object library into the new view (settings its attributes on the right hand panel) and THEN ctrl dragged from the tab bar controller to the new view, creating a relationship segue.
If I tried to ctrl drag from the tab controller without first adding a tab item to the new view, it had the behaviour you described.
be sure to check the size of your icon image.
the tint of image added is grey by default. If you have a large sized tab bar image, it can look like the whole tab bar is greyed out for some reason. pic does not auto resize.
bellow process is follow in Xcode 9.4 for adding new item in tab bar controller.
1)Drag and Drop new Tab Bar Controller into sotrtyboard
2)It will show 2 item which connected with 2 view controller.
3)For adding third item button in tab bar controller
i) Add new View Controller.
ii) Right click on Tab Bar Controller and Drag into new view controller.
iii) one option popup will display inside that popup select "view controllers" options
It will create relationship link and will generate automatic item button in tab bar controller.
need to add/drag icon (from showing the media library) to the 3rd view controller, so that it can display properly.
Restarting Xcode 6.1.1 solved the issue for me while I was working on multiple projects.
go t0 library and choose tabbar controller then drag and drop after that take another uiviewcontroller and then click on tabbar and control and right click then drag and drop in the uiviewcontroller then you see some options where you have to choose in the relationship segue -> view controller

How to connect the UITabBarController to 3 different screens?

I just created the UITabBarController and then I embedded the NavigationController into it.
The issue I am having now is that I am not sure how to add tab bar items. Right now I just have one item that goes to the home screen. But what do I do to add tabs to that tabbarcontroller?
I tried control-dragging it to other controllers, but I think that is not the way to go here.
Could someone please point me in the right direction.
Tab bar items are automatically added based on how many view controllers the UITabBarController has.
For example when you call:
self.tabBarController.viewControllers = #[viewController1, viewController2];
2 tab bar items will be created automatically for you.
I assume you're using Storyboards.
If you right click on the Tab Bar view controller connections icon (the round golden icon on the left) or select the connections inspector (on the right) while you've got your navigation controller selected in the storyboard you'll see a "View Controllers" option under "Triggered Segues". Simply drag from that circle to the new view controller you want to be linked in your tab bar controller and voila, new tab bar item.
You can also do all of that from the beginning. If you start a project that is a tabbar project you will automatically get two tabs. If you want more, drag a view controller over from the right pane under objects. Then control click and drag from the root view to the new view controller and select relationship tabbar. You can hook up as many as you want without the code. Hope this helps you out.
