Table view in UIViewController doesn't get hidesBarsOnSwipe functionality

Question

I have a table view as the first child of a regular UIViewController. I've tried adding the navigation controller's barHideOnSwipeGestureRecognizer gesture recognizer to both my view and table view, but no dice. In the snippet below, blah: is never getting called.

[self.navigationController setHidesBarsOnSwipe:YES];
[self.tableView addGestureRecognizer:self.navigationController.barHideOnSwipeGestureRecognizer];
[self.navigationController.barHideOnSwipeGestureRecognizer addTarget:self action:@selector(blah:)];

I feel like the barHideOnSwipeGestureRecognizer is the way to tap into this nice functionality when not using a top level scroll view controller (collection or table), but I can't figure out exactly how.

Answer 1

If you want to hide navigationbar on swipe, meaning when you scroll your tableview in upward direction (goes to down) then

 self.navigationController.hidesBarsOnSwipe = YES;

is enough to achieve this. It will hide the navigationbar and show it again on tap . Make sure you have set proper constraint to tableview . your constraint should be top,bottom,leading and trailing with constant of 0 with nearest neighbor .
