This code is working on iOS9, 10 (tested)

    func hidePageNumberView(v: UIView) {
        for subView in v.subviews {
            if subView.isKindOfClass(UIImageView) || subView.isKindOfClass(UILabel) || subView.isKindOfClass(UIVisualEffectView){
                subView.hidden = true

                if subView.isKindOfClass(UILabel) {
                    if let sv = subView.superview {
                        sv.hidden = true
                    }
                }
            } else {
                hidePageNumberView(subView)
            }
        }
    }

Implement webView.scrollView.delegate and run above code in scrollViewDidScroll

Hope this help.

iOS 11 / Swift 4:

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    hidePageNumberView(scrollView)
}

func hidePageNumberView(_ v: UIView) {
    for subView in v.subviews {
        if subView is UIImageView || subView is UILabel || subView is UIVisualEffectView {
            subView.isHidden = true

            if subView is UILabel {
                if let sv = subView.superview {
                    sv.isHidden = true
                }
            }
        } else {
            hidePageNumberView(subView)
        }
    }
}
