我想在我的React Native项目中使用SVG图标。我要求它像：
var svg = require('../images/Upvote.svg');
但是我收到了这个错误：
无法解析模块../images/Upvote.svg /path/to/my/project/js/Component.js：目录无效 /path/to/my/project/images/Upvote.svg
我想在Xcode项目设置中添加/更改内容吗？
顺便说一句，如果我使用PNG图像，一切都很好，没有错误..答案 0 :(得分：4)
此时React Native不支持SVG。有一些图书馆在那里他们玩这个想法，但我不知道他们中的任何一个是“生产准备好”
答案 1 :(得分：1)
我使用react本地SVG和一个我自己的小组件来显示SVG。 如果文件SVG太多，我认为icoMoon的解决方案会更复杂但会更好。 解决方案在这里： Which is the best approach to insert an vector (svg) graph into a react native application
这是我自己的组件，通常在我的应用中只使用少量SVG文件时使用。

</Svg>;
const SvgAssets = function(props){
const {icon, width = 80, height = 80} = props;
const lib = {
'car-park-sensor': CarParkSensor
};
const Element = lib[icon];
if(!Element){
throw new Error(`SvgAssets doesn't have any icon with name ${icon}. Please insert a valid icon`);
}
return Element(width, height);
};
export {SvgAssets}
然后您可以通过这种方式使用
<SvgAssets icon="car-park-sensor" width="190" height="190" style={{alignSelf:'center'}} />
