I am building an iPad app which basically has a UITabController which controls and displays 2 UIViewControllers that I set via: 

```
[tabBarController setViewControllers:
[NSArray arrayWithObjects:browserController, videoController, nil]]; 

```

I would like to add a 3rd button to the UITabBar that presents a Popover when clicking it. 
I have no idea how to do this...

I tried a couple of things like:
(in .h) 

```
UITabBarItem *bbiOpenPopOver;

```

(in .m) 

```
[bbiOpenPopOver setTitle:@"test"];
tabBarController.navigationItem.rightBarButtonItem = bbiOpenPopOver;

```

But I guess I was way off, this did nothing visible...

How can I add an item to a UITabBar by code, that will present a Popover?

Thank you for any feedback and/or pointers.
