Handling scrolling nested UIScrollViews scrolling in the same direction

I am trying to implement something similar to Twitter iOS App (profile page)

This is view hierarchy:

• UIScrollView

  • Custom View
  • UITableView

  During scroll, once UIScrollView reaches certain y offset, (when UITableView gets to the top of the screen), then UITableView should start scroll. This needs to work in one continuous motion.

By default, this is not in continuous motion.
