我添加了 Unrar4iOS 框架并出现以下链接器错误。如何解决这个问题？

该错误向您表明 Unrar4iOS 既定义在 Unrar4iOS.a 中，也定义为项目中的单个文件。所以去：

TargetSettings->Build Phases->Link Binary with Libraries 并删除 Unrar4iOS。

Unrar 库是用 C++ 编写的。如果您的项目中没有任何 .mm 文件，则 Xcode 不会链接到 C++ 标准库，并且对 C++ 的所有引用都无法链接。

似乎您已经两次添加了同一个库，这就是为什么它说“重复符号 __Z12CallbackProcjlll”

这是一个编译好的测试井框架：Unrar4iOS.framework
