###ScrollView If you have scrollview in the modal and you want to dismiss modal by drag it, you need to set scrollview to ZFModalTransitionAnimator instance.
[self.animator setContentScrollView:detailViewController.scrollview];
###Direction You can set that which direction will our modal present. (default is ZFModalTransitonDirectionBottom)
self.animator.direction = ZFModalTransitonDirectionBottom;
P.S. Now you can set content scrollview only with ZFModalTransitonDirectionBottom

pod "ZFDragableModalTransition"
The current ViewController's view still visible behind the modal, so you just set transparent color to background view.
