The website was developed using the old version of WEEX syntax. It is currently used in WeChat. Customers often report that the web page cannot be checked in or some icons are not displayed. Later, it was discovered that the lower the IOS version, the worse the compatibility, especially IOS8
I would like to ask if this is a flaw in the IOS and WeChat versions? Does weex have any solution for this? Will it be better to upgrade to the vue version of weex
By the way, is this version number 0.4.0weex? 
Use weex -v to see that it is version 1.0

It is recommended to upgrade to the new version
