Question

Xcode给了我以下错误，我真的不知道该怎么做，让我疯狂。我正在导入一个OpenCV框架，所以可能存在问题或与编译器相关的问题。谁能告诉我该怎么做或搜索？

      Undefined symbols:   "_CGImageDestinationCreateWithURL", referenced from:
      cv::ImageIOEncoder::write(cv::Mat const&, std::vector<int, std::allocator<int> > const&)in OpenCV(grfmt_imageio.o)   "_CGImageDestinationAddImage", referenced from:
