嘗試從派生自UIViewController的類繼承時發生錯誤

Question

我開發了一個名爲BaseVC的類，它通過繼承UIViewController類。當我嘗試做一個小的測試應用程序一切正常

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) 

：當我試圖從我的新BaseVC類繼承，我得到這個錯誤。

Answer 1

將您的BaseVC.m加入您的Targets -> Build Phases -> Compile Sources。這應該做的伎倆。
