How to make a "complicated" twitter like case

(label it a question)

I have 2 ViewControllers to use. Basically they contain only a UITableView - like the twitter example - but the thing is that they are completely different (which is not a problem, the delegates can handle it with conditions) But has a lot of extra functionality (catch click on the UITabBar to refresh and scroll up, swipe up to refresh etc.)

I'm having trouble understanding what should I implement - can I have my UIViewController subclass SLPagingViewController? (I can't just add tableview views like the example - it's not enough)

Or should I have 2 UIViewControllers (like the tinder example) and make them share relevant code outside the logic of SLPagingViewController?
