本文指导您如何解决Objective-C与C++文件混编时出现的未知类型名错误，包括设置编译源代码为Objective-C++，修改相关文件扩展名，并在遇到不兼容类型错误时进行类型显式转换。

Select "Compile Source As" variable in compiler settings and set its value to "Objective-C++" i.e Build Settings->Apple LLVM 7.0 - Language->Compile Source As->Objective-C++ (in Xcode 7.1)
Change the relevant files which include a C++ header file from .m to .mm (sometimes you need to change all .m to .mm).
If you face incompatible type errors, explicitly do type casting of the required type. These errors might not have shown up when it was .m file.
