I am learning to program in Swift 4, and I have no problems with the code, but I am working on a project using MVC with XIB design files. A NavigationBar is added to a view, but it does not load the back button to the left of the title.
This is what I want:
Currently, I only have this:
I have not seen your code but it seems you do not have navigation controller.
Add a navigation controller on your storyboard and connect your view controller to it (use segue).

I am working my way through the iOS Big Nerd Ranch book, and have hit a roadblock. This is about the extent of my iOS knowledge. I found a similar question from a few years back, but was not able to implement the solution so maybe my case is different: Programmatically assign view controller to tab bar controller
The Problem: The book has you delete a storyboard controller in order to implement it programmatically. Currently the app is two viewControllers and a Tab Bar Controller to navigate between the two. I deleted the viewController and implemented it in swift according to directions (pictured below), but I am not sure how to link this MapViewController back up with the Tab Bar Controller. Referencing storyboard objects programmatically has not been discussed yet, and I am having trouble piecing the steps together from other online resources.
What Happens When I Run It: My application opens up to the other viewController, which is a storyboard, and the Tab Bar Controller only contains a button for that one viewController.
The Question: What is the appropriate way (where should it be done, and how) to take the viewController I have defined in swift below, and place it in the Tab Bar Controller? Thank you very much for the help!
The storyboard with the MapViewController deleted:
The MapViewController that I want to put in the Tab Bar Controller:
I'm developing a project in Swift and when using the storyboard to modify the views, I find an uncomfortable situation. The image is self-explanatory: Image of the stroyboard.
As you can see, the bar has grown and it's impossible to see the view i'm working in. At first, the error ocurred in the navigation controller beneath the tab bar controller but now it spreads to the new views I create and connect.
Any help would be apreciated.
I have an app which has 5 major user flows..each flow is a few screens linking to each other...so each flow warranties its own storyboard. Each storyboard starts with a custom view controller that is embedded in a navigation controller. So far so good.
Now all of this is "stitched" together via a UITabBarController. This is the most default UI design ever known to iOS.
But turns out I don't really know how to link from tabbarcontroller, which is in its own storyboard (that is set as the main one on code project) to any of the other storyboards.
This problem looks so! simple, so I think I am missing something utterly obvious, but I just can't figure out how to do it.
So how do I link from tab bar controller in storyboard 1 to the initial view controller in storyboard 2 when a tab is tapped?
You should do this in code. You can have the tab bar controller (tbc for short) and the controller in the first tab in the app's main storyboard, and in the app delegate, instantiate the other controllers using instantiateInitialViewController. Create a mutable array by copying the tbc's viewController array, add the other controllers you instantiated to it, and then set that array as the tbc's viewControllers array.
You have to add your viewcontroller programmatically in tabbar.
I am new to iOS development and have not tried this programmatically yet. I would prefer to get this working in a storyboard.
I'm following this somewhat outdated tutorial from XCode 4.5 in XCode 6.1 to create a series of views connected by one navigation controller.

Once I create the second view controller, I am unable to double click the navigation bar to change the name and I am unable to add a bar button to it.
I have a Segue going from bar button "Item" from view 1 to 2. Notice in the "View Controller Scene" there is no navigation item. If I add any elements to the view controller they fall under "View" and not under "View Controller", unlike view controller 1 where it falls under "one".
Is this a limitation on XCode? Am I using the wrong Segue (Show)? Is there a hidden setting or customization I'm missing?
I actually have this working for 2 view controllers and failing the 3rd in a separate project but I don't know what I did to do that so I'm pretty sure it's possible I just cannot reproduce..
EDIT: Workaround Instead of the new adaptive SHOW segue, use the deprecated PUSH segue, add the bar button items, then change back to the adaptive SHOW segue.
Try adding a Navigation Item to the controller and it should work properly
I have built some view controllers in storyboard like in the picture below
I already implemented the data inside them, modal segue is used for transitions in between. Now I just realise when I push "back" button, previous view won't be properly loaded. I figure I should switch to navigation controller and add those controllers in stack instead. But I don't know how to go from where I am now.
I think I should make changes programmatically because I found building navigation controller in storyboard won't have much variation in UI design (at least I don't know how to implement existing pages in that way). So what should I do to implement programmatically? Please help me, thanks!
Select Category View Controller and go to menu: Editor > Embed In > Navigation Controller. Then change segues style from Modal to Push.
