Navigation bar on iPhone popover - ios

Question

I don't ask for a lot out of life, but I'd give a lot to know how to get a navigation bar on this popover:
Here's my storyboard:
And here's my code presenting the popover:
#IBAction func doButton(_ sender: Any) {
let vc = PopViewController()
vc.preferredContentSize = CGSize(width: 260,height: 300)
vc.modalPresentationStyle = .popover
vc.view.backgroundColor = UIColor.green
if let pres = vc.presentationController {
pres.delegate = (self as UIAdaptivePresentationControllerDelegate)
}
self.present(vc, animated: true)
if let pop = vc.popoverPresentationController {
pop.sourceView = (sender as! UIView)
pop.sourceRect = (sender as! UIView).bounds
pop.backgroundColor = vc.view.backgroundColor
}
}
}
extension ViewController : UIPopoverPresentationControllerDelegate {
func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle {
return .none
}
}
(Thanks to #matt, BTW, for the above code!)
I've searched high and low on Google yet haven't found an answer that I could understand. I tried to add the nav bar in Storyboard, but no dice--the only element that would accept it was the prototype cell in the table view.
Please don't redirect to something written 7 years ago--I've already read most of them, and I'm using Swift now. Certainly, I may have overlooked a clear answer, and I'll be humble and contrite if that's the case. But meantime, I'd sure appreciate some help if ya got it!
Thanks!

Answer 1

Change your right tableview controller to a navigation controller with a tableViewController root. The navigation Controller gets an identifier : "navigation".
Now you can change the first code of doButton function, and keep the rest.
#IBAction func doButton(_ sender: Any) {
let vc = self.storyboard?.instantiateViewController(withIdentifier: "navigation") as! UINavigationController
vc.preferredContentSize = CGSize(width: 260,height: 300)
vc.modalPresentationStyle = .popover
vc.view.backgroundColor = UIColor.green
if let pres = vc.presentationController {
pres.delegate = (self as UIAdaptivePresentationControllerDelegate)
}
self.present(vc, animated: true)
if let pop = vc.popoverPresentationController {
pop.sourceView = (sender as! UIView)
pop.sourceRect = (sender as! UIView).bounds
pop.backgroundColor = vc.view.backgroundColor
}
}
finally , you will get the nav bar in your popover.
