objective-c - NSWindowFlipper 构建错误

Question

我正在尝试使用 Mizage 的 window flipper library在我的 Mac 应用程序中。

当我尝试构建它时，出现以下错误:

Undefined symbols for architecture x86_64:
"_kCAGravityCenter", referenced from:
  -[NSWindow(Flipper) flipWithArguments:] in NSWindowFlipper.o
"_CATransform3DMakeRotation", referenced from:

  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)

我的基础 SDK 是 10.7 并且启用了 ARC。我是 Cocoa 的新手，以前没有见过这种错误。有人可以建议这里有什么问题以及如何解决它吗？谢谢。

您需要链接 QuartzCore 框架。
