Question: My tabbar have more than 6 items,when I click [more] item,it will show other items with a tableview.

Then click the one of items,I hide the navBar use `setNavigationBarHidden:YES` in `viewDidLoad`,and I have a custom button click to back [more] use `popViewControllerAnimated:YES`.

When it back,the navBar still hiding,how can I show the navBar recover on [more] screen?(I need the EDIT button in [more])

Answer: 
I have the idea to use `Html Agility Pack` to parse html. 

```
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);  // this is your string
var divs = doc.DocumentNode.Elements("div")
      .Select(div => string.Format("<div>{0}</div>", div.LastChild.InnerText));

```
you can use regex

```
    string val = @"<div><span class=""help"">This is text.</span>Hello, this is text.</div><div>I have a question.<span class=""help"">Hi</span></div>";
        Regex reg = new Regex("<span .+?</span>", RegexOptions.IgnoreCase | RegexOptions.Singleline);
        string ret = reg.Replace(val, "");
        Debug.WriteLine(ret);

```
