一个选项卡栏控制器中多个选项卡的一个导航控制器

Question

I am looking to have one Navigation Controller that will be atop multiple Tab Views in a Tab Bar Controller.

This Navigation Controller will have an Info button in the top right that will segue to the same view no matter what view the user is on (VC 1 / 2 / 3).

Here's what I have set up in storyboard so far:

The Problem: The red Nav bar is only accessible through "First VC."

What I need: I need the red Nav bar to be accessible through ALL the tab views. (First VC / VC 1 / VC 2 / VC 3).

What I researched: I read that you can simply embed each tab view in a Navigation Controller. The problem I foresee here is bad re-usability of the navigation bar. That red bar will need to be created 4 times, and each of those 4 buttons will have to link to the same view 4 times.

What is the best approach for having ONE navigation bar that is accessible through ALL the Tab Views.

Thanks.

This has been resolved. What I ended up doing was embedding EACH VC that has a Tab Bar Item in its own Navigation Controller (in my original post, these are Green VC 2 / Blue VC 3 / Tan VC 4). As @JohnD pointed out in his comment, this gives me much more flexibility on customizing the Nav bar for each tab.

Regarding my Button concern: Each of the nav bars have a settings button. Instead of cluttering up the Main storyboard with multiple segues to the Settings VC, I created a new storyboard. Within this storyboard, I have a Settings View Controller with all the functionality and options needed. The buttons instantiate this new VC with code, as seen in this post: How to push and present to UIViewController programmatically without segue in iOS Swift 3
