问题简述

１．项目中使用的 svg 在苹果手机移动端，微信内置链接打开显示模糊。
２.　经过查找资料，可以使用＜object＞标签来嵌套 svg 可以解决 svg 模糊问题。
３.　使用＜object＞标签引发的问题，部分 svg 失去了点击事件的功能，经查证，不能点击的 svg 是因为在＜object＞标签内的点击事件失效，把点击事件添加到父级元素即可。
４.　经过一天时间，大量的 svg 不显示，原因是＜object＞标签存在浏览器兼容问题，在手机其他浏览器中均可正常显示，但是使用微信内置的浏览器打开 svg 就不显示。

问题分析

移动端微信的浏览器打开 svg 模糊的原因不是由 svg 包裹的标签导致的，于是与＜object＞标签没有关系，解决方向错误，真正的问题出在 svg 本身，经查证显示模糊的 svg 都使用了滤镜 filter，但是微信内置的浏览器并不支持 filter 属性，如下所示：

解决方法

解决方法就是删除 svg 的 filter，包括 filter 的各种属性链接，下面列出结果案例：
这种是全部删除只把需要的填写上去，自己可以试着调，transform 是里面组合 svg 的位置。

这一种是只需要把 filter 相关属性全部删除，在 里面改一下填充颜色就行了，也就是fill 属性 改成自己需要的 svg 颜色，有的需要把 transform 调一下。
