【问题描述】：
我目前正在为我的 iOS 应用程序开发 html 富文本编辑器，所以，设置很简单，我有一个 UIWebView 加载我的编辑器代码，html 输入是一个 'contentEditable' DIV .
问题是每次我选择这个div输入一些文本时，输入框上会出现一个浅灰色框，告诉用户该文本字段已被选中。
注意：效果可以看这个快video
我的问题是：如何去掉这个浅灰色框？
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>

@StephenJ 发表评论后，我意识到这个灰色框架可能是 UIWebView 的子视图，而不是 css 属性。我在框架出现的那一刻从 UIWebView 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，我发现了一个名为UIHighlightView 的子视图，正如名称所证实的那样，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？
【问题讨论】：
-
你试过
-webkit-appearance:none吗？ -
尝试将
outline: none;添加到输入:focus伪元素中。 -
@Bluey 我已经尝试过了，但没有成功！
-
@pbibergal 我试过这个 wright 现在它不起作用了！
-
首先，我会观察 webView 上的子视图，以确定是否添加了原生子视图，或者它是否在网页渲染器上。这是“我不知道”的方法，但它缩小了修复范围。
