打开手机——设置——找到微信——可以进行修改
具体步骤如下：
-
打开设置界面：
在IOS系统当中，设置软件的提示音，都要进到设置当中，虽然看起来很枯燥，但是也非常的便利，打开设置可以完成应用程序的所有访问、声音的设置。
-
设置当中找到微信的应用程序：
在设置的最下面的列表当中，会有我们安装着的可以设置的应用程序，我们要修改的微信自然也在里面，点开之后我们可以进行访问、以及是否提示的修改。
-
开启微信声音的通知：
打开微信的程序设置之后，首先确保应用程序可以正确的访问手机的各项功能，这可以完整的使用微信，既然要设置提示音，千万不要忘了开启声音的选项哦。
-
打开声音的设置：
在微信的应用程序当中设置完了之后，重新退出回到设置当中，然后在设置界面当中找到声音的选项，找到软件的提示音类型，然后点进去进行修改（新通知）
-
修改提示音的类型：
点进去修改新通知的提示音的时候（所有软件的推送的通知，都可以通过这个修改）可以看到有很多的类型， 点击是可以进行试听的，选择之后再确定。
-
在微信的设置当中查看：
在设置当中确定好了之后，我们也可以打开微信的设置，在新消息通知当中确认一下是不是打开了消息通知，特别是声音的开关，再进行一次检查。
-
方法适用其他应用程序：
在设置当中查看应用程序，并且开启新通知的声音提示，之后回到声音当中筛选适合的提示音，这个操作的方法，不仅仅可以用在微信上面，其他应用程序也可以哦。
iOS11文件管理神器Filza可以在未越狱设备上修改系统文件，包括替换系统文字、修改滑块文字等等，当然，也可以修改微信提示音。
Filza的适用范围是搭载iOS11.0-11.1.2的64位设备，未安装的朋友可以在爱思助手官网下载“Filza”进行安装（下载地址：https://www.i4.cn/news_detail_17759.html）

然后将自己喜欢的微信提示音资源in.caf文件上传到百度云，手机百度网盘下载文件in.caf，选择用filza打开，长按in.caf文件进行复制，接着找到路径/var/containers/Bundle/Application/com.tencnet.xin/WeChat.app/ 先将原文件in.caf重命名以便后续恢复，然后粘贴刚下载的文件即可生效，无需重启设备。
