ios - 单元测试 Xcode 4 的链接器错误

Question

我的应用程序在运行时构建良好，单元测试也构建良好

当我为 CGAffineTransform 添加一些代码时，单元测试失败(应用程序仍然正常)

模拟器和设备的行为相同

错误信息:

Undefined symbols for architecture i386:
  "_CGAffineTransformMakeTranslation", referenced from:
      -[PhysicsObject hasPoint:] in PhysicsObject-23B4A02B8F0621AD.o

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已经尝试过来自

没有任何效果 :( 我怀疑这与一个框架有关，特别是没有找到。我似乎无法确定是哪个框架。非常感谢帮助。
