Slide down to dismiss presented navigation controller

Question

I want to implement slide down interaction and dismiss view controller, for which i referred this link , but this works only for dismissing a single view controller presented from view controller.

In my case, i have presented a navigation controller as user can push to another view from that view controller, but drag down to dismiss doesn't work with navigation controller.

UPDATED:It should work as - slide down gesture is triggered from any of the screens, (for eg: from main screen or pushed screen/detail screen) the navigation controller should dismiss completely.

Please suggest if anyone has come across implementing the same.

Thanks in advance.

You need to show what you are doing in order for someone to figure out what's missing. Please share your code — Malik
I have used the same code from the link which i have linked in the question,created ViewControllerPannable class, and used it, but it doesnt seems to work. — khushboo
One thing to keep in mind is that a modal controller and a navigation controller have different ways of dismissing a controller. For a modal controller, you would use dismissViewController whereas in a navigation controller, you would use navigationController.popViewController (because it is pushed onto a navigation stack) — Malik
i have to implement as - on swipe down or panning down the view controller it should dismiss whole navigation controller. — khushboo

You can add PanGesture in your navigation controller. Using - (CGPoint)velocityInView:(UIView *)view you will know in which direct user panned. if view was panned down manage its constraint accordingly and if it is more than a threshold value pop that view.
