从iOS上的htmlinput中删除select灰色阴影
我目前正在为我的iOS应用程序的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，HTMLinput是一个'contentEditable'DIV 。
问题是每次我select这个div来input一些文本时，input框上会出现一个浅灰色的框，告诉用户文本框已经被选中。
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的框架？
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> // ———————————————— ————————————————– —————-编辑1 —–
@StephenJ的评论后，我意识到，这个灰色的框架可能是UIWebView的子视图，而不是一个css属性。我logging在UIWebView的视图层次框架出现的时刻，这是日志：

分析UIHighlightView所有这些子视图后，我发现一个名为UIHighlightView ，名称确认，这个视图可能会突出显示webView.So我的第二个问题是： 如何删除此视图？
就像设置下面的CSS规则一样简单。
div { -webkit-tap-highlight-color: rgba(0, 0, 0, 0); }
这使得应用的阴影透明，所以它似乎已经消失了。
