ios - CGContext 的 Apple Mach-O 链接器错误

Question

这个错误让我发疯，知道吗？

架构 armv7s 的未定义符号：

"_CGContextConcatCTM", referenced from:
  -[PopoViewController onClick:] in PopoViewController.o
"_CGContextTranslateCTM", referenced from:
  -[PopoViewController onClick:] in PopoViewController.o
"_CGContextSaveGState", referenced from:
  -[PopoViewController onClick:] in PopoViewController.o
"_CGContextRestoreGState", referenced from:
  -[PopoViewController onClick:] in PopoViewController.o

ld: symbol(s) not found for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)

带有库的二进制文件是链接的。库搜索路径正确。

谢谢

将您的应用程序与 iPhoneOS 架构的 CoreGraphics.framework 链接。
