如何更改 swift 中现有 HTML 字符串的样式？
How to change the styles of existing HTML string in swift?
我从 Web 服务获取 HTML 字符串并将其加载到 `UIWebView.示例 html 字符串是这样的。
" <div class='wg-rs-workAnniversary'> <div class='greetingtext'><span class='years work-years'>1 <sup>-</sup></span> <span class='event'>Work <br> Anniversary</span></div> <input type='hidden' class='hid-work-years' value='1'/> </div> <div class='wg-rs-btext work-years'>ABC Employee celebrates his 1<sup>-</sup> work anniversary today</div>"
加载后，它只是一个黑色文本。我想增加这些文本的大小，更改颜色并将其居中放置在 UIWebView 上。我如何在 swift 中执行此操作？请帮助我。
你可以通过在 html 字符串中附加样式来实现。
let htmlText = " <div class='wg-rs-workAnniversary'> <div class='greetingtext'><span> class='years work-years'>1 <sup>-</sup></span> <span> class='event'>Work <br> Anniversary</span></div> <input type='hidden'> class='hid-work-years' value='1'/> </div> <div class='wg-rs-btext> work-years'>ABC Employee celebrates his 1<sup>-</sup> work anniversary> today</div>"
let htmlTextWithStyle = htmlText + ("<style>body{font-family: '\(UIFont.systemFont(ofSize: 12.0))'; font-size:\(14.0);}</style>")
要使其居中，您可以在 html 字符串中添加以下内容
"<style type='text/css'>html,body {margin: 0;padding: 0;width: 100%;height: 100%;}html {display: table;}body {display: table-cell;vertical-align: middle;padding: 20px;text-align: center;-webkit-text-size-adjust: none;}</style>"
