NSWindowFlipper构建错误

Question

我想在我的Mac应用程序中使用Mizage的window flipper library。

当我试图建立它，会出现以下错误：

Undefined symbols for architecture x86_64: 
"_kCAGravityCenter", referenced from: 
    -[NSWindow(Flipper) flipWithArguments:] in NSWindowFlipper.o

    objc-class-ref in NSWindowFlipper.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我的基地SDK为10.7和启用ARC。我是可可的新手，并没有看到过这种错误。有人可以建议这里有什么问题，并可能如何解决它？谢谢。
