title: Call C function using Objective C class instance
body: <p>I have an Objective C class with a C type method in it. I have to link a C++ library and a C library with my code. If I make the library calls from any Objective C function, I get linker errors, that it can't find the symbols.</p>
  
  <p>refer <a href="https://stackoverflow.com/questions/12816983/using-c-static-library-in-objective-c/12817609">using c++ static library in objective c</a></p>
  
  <p>But I need to call that C function somehow. Is there any alternative? In case of only C libraries, I could make the library calls from objective C method, but C++ library doesn't allow me to do that. I don't know why.</p>
