我正在使用最新版本的opencv ( opencv 2.4.9 )，并且必须具有Core Plot (绘图框架)所需的-ObjC 标志。

当我在其他标志中设置-ObjC时，我得到了很多类型的错误（实际上是 28 个）：Undefined symbols for architecture i386如下：

Undefined symbols for architecture i386:
"_CMSampleBufferGetImageBuffer", referenced from:
-[CaptureDelegate captureOutput:didOutputSampleBuffer:fromConnection:] in opencv2(cap_avfoundation.o)
CvCaptureFile::retrieveFramePixelBuffer() in opencv2(cap_avfoundation.o)

... etc

这是与Bartosz Bialecki相同的问题，我尝试了建议的解决方案，但问题仍然存在。

有人有想法吗？
