是否可以删除[“第20页的第1页"显示pdf时在UIwebview中查看[view]? [英] Is it possible to remove ["Page 1 of 20" view] in a UIwebview when displaying pdf?

问题描述

经过大量谷歌搜索后，我无法解决问题. 我有一个带有PDF的UIWebView.

I can not get to a solution after much googling. I have a UIWebView with a PDF in it.

我不希望使用以下视图:第1页，共20页"查看PDF文件时位于左上角的小视图. 可以删除这个吗?

I do not want the view: "Page 1 of 20" The small view in the upper left corner when viewing a PDF file. It is possible to remove this?

推荐答案

Swift 3和WKWebView

Swift 3 and WKWebView

我得到了WKWebView的所有子视图，然后删除了WKPDFPageNumberIndicator:

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
}

您可能必须设置webView.navigationDelegate = self

更新(未测试)-Swift 4

保持上面的getSubviewsOfView功能并修改webView功能，如下所示:

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
    }
  }
}
