Imitate Facebook hide/show expanding/contracting Navigation Bar

by

The solution given by @peerless is a great start, but it only kicks off an animation whenever dragging begins, without considering the speed of the scroll. This results in a choppier experience than you get in the Facebook app. To match Facebook’s behavior, we need to: hide/show the navbar at a rate that is proportional … Read more
