如题，部分ios系统版本较低的手机，目前已知iphone 6s、iPhone 6plus手机上，运行在微信浏览器中的部分页面渲染不出来，白屏；挨个把页面所有东西都删了，发现只要用了link标签引入css，哪怕这个css文件是空的，原本的dom就无法显示了，由于是客户反馈的，找了几部同款手机但是系统是最新的，并没有复现，还是第一次遇到这个问题，没有头绪。。。。。。。。。
还有一个情况也是类似的，也是这两个机型，原本用户能正常访问页面，但是自从加了一个时间倒计时效果，js就不执行了，，，，，之所以说js不执行，是因为js的第一行代码就是移除loading元素，而这2款机型一直显示loading图片。。。。。一开始觉得是倒计时问题，加了try catch，把setInterval换成setTimeout都没用
