Present a UIPopoverPresentationController when a tab item is tapped on UITabBarController

I have an app with 5 tabs on UITabBarController. I want to show a menu (UIPopoverPresentationController) when I tap on last tab. And, when I tap on any Popover menu item, I want to navigate/push to the relevant UIViewController.

Can someone please tell me how can I achieve this? Some one please direct me towards any delegate methods or something please?
