我自己解决了。
原来是场景上MISS了一些脚本文件…
看控制台那些警告发现了蛛丝马迹。。。

[reiayanami]

但是MISS的这些脚本文件，在直接在浏览器运行不会报错，但是BUILD出来就会报错。

[victor.dev.f1 (victor121212)]

确实是脚本丢失导致的，为什么开发环境不报错暂时不知，此问题用时半天。

检查下组件上挂的脚本是不是丢失了。。
描述下我的问题
在 web 环境下运行是没有问题的，
但是在 IOS 真机调试，报 5000 的错（object already destory）
看到个帖子说是脚本丢失的问题，遂去查了下预制物上挂在的脚本，果然有丢失情况
将其删除，问题得到解决。IOS 真机通过

cocos 开发者，路漫漫其修远兮啊，
在 web 上可运行，在真机上报错，这本身就会诱导人的思维的，
