How to set the iphone WeChat chat bubble?

Because the iOS system is relatively closed, it is generally impossible to change the system files, so the original material files (including various png image files with WeChat interface style) in the WeChat App installation directory cannot be changed casually, unless the official version later supports downloading theme packages to change the WeChat theme.

Another method is more complicated, that is, get the root user permission through the jailbreak system, and then manually replace it with the current installation directory of WeChat by finding the material package file Assets.car or batch material picture files made by others, and then restart the WeChat background. If the theme plug-in is installed after jailbreak, you can also switch WeChat themes at any time by installing multiple theme packages. However, since jailbreaking will reduce the security of the system, it is not recommended here.
