Is it possible to remove ["Page 1 of 20" view] in a UIwebview when displaying pdf?

Swift 3 and WKWebView

I get all the subviews of the WKWebView and then remove WKPDFPageNumberIndicator:

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
  let webViewSubviews = self.getSubviewsOfView(v: self.webView)
  for v in webViewSubviews {
    if v.description.range(of:"WKPDFPageNumberIndicator") != nil {
      v.isHidden = true // hide page indicator in upper left
    }
  }
}

func getSubviewsOfView(v:UIView) -> [UIView] {
  var viewArray = [UIView]()
  for subview in v.subviews {
    viewArray += getSubviewsOfView(v: subview)
    viewArray.append(subview)
  }
  return viewArray
}

You'll probably have to set webView.navigationDelegate = self

UPDATE (not tested) - Swift 4

Keep the getSubviewsOfView function from above and modify the webView function like this:

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
  let webViewSubviews = self.getSubviewsOfView(v: self.webView)
  for v in webViewSubviews {
    if v.isKind(of: UILabel.self) || v.isKind(of: UIImageView.self) || v.isKind(of: UIVisualEffectView.self) {
      v.isHidden = true
    }
  }
}
