title: Is it possible to subclass UITableViewController with xib or storyboard?
body: <p>It is easy to subclass UITableView. Also my UITableViewController can inherit BaseTableViewController programmatically instead of xib. But the requirement is using xib or sb to subclass. Is it possible? I have tried to drag a UITableViewController in a xib. And Xcode remind me the customization only can be done in storyboard.But in storyboard , children controllerA is connected to its parent controller. And children controllerA inherit from baseController. BaseController needn't to connect anything with  segue. Am I right?</p>
