我创建了一个新的应用程序项目(不是库或框架),然后我将"compile source as"设置为object-C++.但是当我编译源代码时,它显示"build failed".
错误是:
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_UIResponder", referenced from:
_OBJC_CLASS_$_AppDelegate in AppDelegate.o
"_OBJC_METACLASS_$_UIResponder", referenced from:
_OBJC_METACLASS_$_AppDelegate in AppDelegate.o
"_UIApplicationMain", referenced from:
_main in main.o
"_OBJC_METACLASS_$_UIViewController", referenced from:
_OBJC_METACLASS_$_ViewController in ViewController.o
"_OBJC_CLASS_$_UIViewController", referenced from:
_OBJC_CLASS_$_ViewController in ViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
但令我困惑的是:如果它是一个框架项目,它编译得很好.你能救我一把手!
