Question

我目前正在为我的iOS应用程序开发html富文本编辑器，因此，设置很简单，我有一个UIWebView加载我的编辑器代码，html输入是＆＃39; contentEditable＆＃ 39; DIV

问题是每次我选择此div输入一些文本时，输入框上会出现一个浅灰色框，告诉用户文本字段已被选中。

注意：您可以在此快速video

中看到效果

我的问题是：如何删除这个浅灰色框架？

我的html文件如下：

<html>

<head>

    <style type="text/css">

        :focus{

            outline:0px solid transparent;

        }

        DIV::-moz-focus-inner {
            background-color:#ff0000;
            border: 0;
            padding: 0;
        }

        ul{
            margin-left:-10px;
        }
        ol{
            margin-left:-10px;
        }

        blockquote {

            border-left:#ff0000 5px double;
            margin-left:0px;

        }

    </style>

</head>

<body onload="addImgAttributes();checkBlockquote();" topmargin="0" bottommargin="0" leftmargin="0" rightmargin="0">

    <div
        id="content"
        class="content"
        contenteditable="true"
        style="font-family: Helvetica; background-color:#fff; color:#000; height:258px;"
        autocapitalize="off"
        autocorrect="off"
        autocomplete="off"
        spellCheck="false"
    >
    </div>

</body>

</html>

在@StephenJ的评论之后我意识到这个灰色框架可能是UIWebView的子视图而不是css属性。我在UIWebView的框架出现的确切时刻记录了视图层次结构，这是日志：

在分析了所有这些子视图后，我找到了一个名为UIHighlightView的名称，因为名称确认，此视图可能会突出显示webView。所以我的第二个问题是：如何删除此视图？ < / p>

Answer 1

就像设置以下CSS规则一样简单。

div {
    -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}

这会使应用的阴影变得透明，好像它已经消失了。

编辑：这是demo link。

从iOS上的html输入中删除选择灰色阴影
