How to hide the navigation bar and toolbar as scroll down? Swift (like myBridge app)


Try this simple approach: Tested in Swift 3

    func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {    if(velocity.y>0) {        //Code will work without the animation block.I am using animation block incase if you want to set any delay to it.        UIView.animate(withDuration: 2.5, delay: 0, options: UIViewAnimationOptions(), animations: {             self.navigationController?.setNavigationBarHidden(true, animated: true)             self.navigationController?.setToolbarHidden(true, animated: true)            print("Hide")        }, completion: nil)    } else {        UIView.animate(withDuration: 2.5, delay: 0, options: UIViewAnimationOptions(), animations: {             self.navigationController?.setNavigationBarHidden(false, animated: true)            self.navigationController?.setToolbarHidden(false, animated: true)            print("Unhide")        }, completion: nil)          }   }

Output: Updated

Note: If you passing any data from this VC to another VC that embedded with navigationController.You may need to unhide the NavigationBar.


Easily to do this:

navigationController?.hidesBarsOnSwipe = true


In my opinion the proper way to handle navigation bar in Tableview as follows. This would applicable if we have section header in Tableview.

func scrollViewWillBeginDecelerating(_ scrollView: UIScrollView) {   if scrollView.panGestureRecognizer.translation(in: scrollView).y < 0 {      navigationController?.setNavigationBarHidden(true, animated: true)   } else {      navigationController?.setNavigationBarHidden(false, animated: true)   }}
