javascript - 在 Obj C 中，如何添加 SVG 蓝图图像并从 UIWebView 渲染数据？
<p><p>我已将 SVG 图像加载到 UIWebView 中，但没有发生从 SVG 图像的选择位置渲染数据的工作魅力。即使我被搜索了更多关于我没有得到任何关于这个功能的信息。同样，我尝试过 SVGKit，但我不了解 SVGKit 的完整场景，所以我选择 UIWebView 的原因。如果有人知道这个功能，请在此处发表评论。 </p>

<p>the SVG map seems like below one.i found few link about SVG image but those are not loading by UIWebView. <a href="https://github.com/SVGKit/SVGKit" rel="noreferrer noopener nofollow">SVGKIT</a> & <a href="https://github.com/chensheng12330/SVGKitDemo" rel="noreferrer noopener nofollow">chensheng12330/SVGKitDemo</a></p>
