我在UIwebview中加载了html文件，并将以下代码放在html文件中。

I have load html file in UIwebview and had put below code in html file.

 <style>
  ::-moz-selection { /* Code for Firefox */
              color: red;
              background: yellow;
          }

      ::selection {
          color: red;
          background: yellow;
      }

Yes. I wasted 2 days to resolve this headache issue.Visit This Link and Place JS Code in your JS File.Import it in .HTML file.

下面是它的示例代码。

function highlight(colour) {
var range, sel;
if (window.getSelection) {
    // IE9 and non-IE
    try {
        if (!document.execCommand("BackColor", false, colour)) {
            makeEditableAndHighlight(colour);
        }
    } catch (ex) {
        makeEditableAndHighlight(colour)
    }
} else if (document.selection && document.selection.createRange) {
    // IE <= 8 case
    range = document.selection.createRange();
    range.execCommand("BackColor", false, colour);
}}

通过Objective-C代码调用此方法
