xcode接sdk时报错Undefined symbols fo

unity 导出xcode后接环信libHyphenateSDK时build报错Undefined symbols for architecture armv7:
也有Undefined symbols for architecture arm64:

Undefined symbols for architecture armv7:

这个错误以为sdk或者framework不支持armv7或者arm64，我这实际上是缺少framework
这个错误是工程里面没有引用 ImageIO.framework造成的，

环信的libHyphenateSDK.a库依赖ImageIO.framework，结果报错让人无语
