openflow Library iPhone 中的错误

Question

每当我添加openflow库并执行时，都会发生此错误

Undefined symbols:
  "_CATransform3DIdentity", referenced from:
      _CATransform3DIdentity$non_lazy_ptr in AFOpenFlowView.o
     (maybe you meant: _CATransform3DIdentity$non_lazy_ptr)
  "_CATransform3DRotate", referenced from:
      -[AFOpenFlowView(hidden) setUpInitialState] in AFOpenFlowView.o
      -[AFOpenFlowView(hidden) setUpInitialState] in AFOpenFlowView.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

有人对此有任何想法吗？

Answer 1

您需要将

"QuartzCore"框架添加到您的应用程序中。你正在使用的库可能需要此框架，因此你的应用需要导入此框架才能进行编译。

Answer 2

看起来你需要将QuartzCore框架添加到你的项目中。请参阅 Xcode 3.2 的此问题或 Xcode4 的此问题。
