I started with NavCntlr -> ViewA -> ViewB -> ViewC
But now I have NavCntlr -> ViewA -> ViewB -> CustomNavCntlr -> ViewC
(If curious, CustomNavController forces portrait orientation using the technique found here: https://stackoverflow.com/a/31801804/814186)
So, the navigation bar on ViewB has a 'Back to ViewA' button. But after introducing CustomNavCntlr, ViewC does not have a 'Back to ViewB'.
The question: How can I navigate from ViewC to ViewB similar to (from the user's perspective) how I navigate from ViewB to ViewA?
If it helps, ViewC is presented with
[self performSegueWithIdentifier: @"SegueToViewC" sender: self];
And the segue is a Push (though I may use Present Modally since that was the suggestion in the example linked above).
