Swift& UIWebView元素隐藏 [英] Swift & UIWebView element to hide

问题描述

  let url = NSURL（string：http：// 
 www.myresponsivesite.fr/section/）; 
 let requestObj = NSURLRequest（URL：url！）; 
 webView.loadRequest（requestObj）; 
  

它的工作完美，但我想把一些div和其他元素放在display none中。所以我的问题是：我怎样才能从我的应用程序快速注入一些CSS？
Thanks。

解决方案

我终于找到了另一种方式，我将html加载到一个变量中，以display：none为例：

  let urlDeBase =http：// mywebsite / section /
如果让url = NSURL（string：urlDeBase）{
 var error：NSError？ 
 let myHTML = String（contentsOfURL：url，encoding：NSUTF8StringEncoding，error：& error）
  

<

  let mystring = myHTML？.stringByReplacingOccurrencesOfString（< h3 class = \myclass \Menu< / h3>，withString：< h3 class = \myclass \style = \display：none \> Menu< / h3>）
 webvieww.loadHTMLString（mystring，baseURL：nil）
  

I got a UIWebView and I load the content like that

let url = NSURL (string: "http://www.myresponsivesite.fr/section/");
    let requestObj = NSURLRequest(URL: url!);
    webView.loadRequest(requestObj);

It's working perfectly but I would like to put some div and other elements in display none. So my question is : How can I inject some css from my app with swift? Thanks.

解决方案

I finally found another way, I load my html in a variable and, i replace some div with a "display:none" exemple :

 let urlDeBase = "http://mywebsite/section/"    
    if let url = NSURL (string: urlDeBase){
        var error: NSError?
        let myHTML = String(contentsOfURL: url, encoding: NSUTF8StringEncoding, error: &error)

and I replace what i want

 let mystring = myHTML?.stringByReplacingOccurrencesOfString("<h3 class=\"myclass\">Menu</h3>", withString: "<h3 class=\"myclass\" style=\"display:none\">Menu</h3>")
 webvieww.loadHTMLString(mystring, baseURL: nil)
