尝试从派生自UIViewController的类继承时发生错误

Question

我开发了一个名为BaseVC的类，它通过继承UIViewController类。当我尝试做一个小的测试应用程序一切正常

Undefined symbols for architecture armv7s: 
"_OBJC_METACLASS_$_BaseVC", referenced from: 
_OBJC_METACLASS_$_ClassX in ClassX.o 
"_OBJC_CLASS_$_BaseVC", referenced from: 
_OBJC_CLASS_$_ClassX in ClassX.o 
ld: symbol(s) not found for architecture armv7s 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

：当我试图从我的新BaseVC类继承，我得到这个错误。

Answer 1

将您的BaseVC.m加入您的Targets -> Build Phases -> Compile Sources。这应该做的伎俩。
