Select UIViewController directly from UITabBarController and via UINavigationController

I start my App with a Tab Bar Controller [TBC]. I use one Item1 to select VC1 (embedded in a Navigation Controller NC), via a view controllers segue. VC1 is connected to VC2 via a Show segue. Item2 of the TBC should be linked directly to CV2 (via view controllers segue).

TBC - Item1 -> NC -> VC1 +> VC2
        |                |
      Item2 -------------+

2 possibilities:

  1. If I connect the TBC to VC2 using view controllers segue (like shown above), I loose my top screen navigation bar in VC2 (if Item2 is used), which would allow me to return to CV1 (which is desired).

  2. If I make a second view controllers segue from TBC to VC1, I could create a custom class of UINavigationController, which could determine which segue (Item1 or Item2) was selected. If Item1 is selected, VC1 should be shown. If Item2 is selected, VC2 should be shown. First, I don't know how I can determine in my custom class of UINavigationController, how to determine which of the 2 segues was selected. Also the item icons and titles of Item1 and Items2 are identical (which is not desired!) and I don't see any possibility to change only icon/title of Item2 and leave icon/title of Item1 as it is.

How can I connect Item2 to VC2, keeping the VC2 navigation bar, and having a different than Item1 icon/title for Item2?

You can use segue identifier to distinguish between two segues.

You can specify segue identifier by selecting segue and go to identifier id in right panel.
