Rewrite func reloadData(), Set scrollView. contentInset based on the frame value of titleLabels.last

I was unsuccessful in centering content with the above instructions. What I tried:

        // Center
        if let lastFrame = titleLabels.last?.frame {
            scrollView.contentInset = UIEdgeInsetsMake(lastFrame.origin.x,
                                                       lastFrame.origin.y,
                                                       lastFrame.height,
                                                       lastFrame.width)
        }
