问题描述

经过多次谷歌搜索后，我无法找到解决方案.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.

我不想要视图:第 1 页，共 20 页" 查看 PDF 文件时左上角的小视图.可以去掉吗?

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

我得到 WKWebView 的所有子视图，然后删除 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
}

您可能需要设置 webView.navigationDelegate = self

更新(未测试)- Swift 4

保留上面的 getSubviewsOfView 函数并像这样修改 webView 函数:

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
    }
  }
}
