"PluginFacebook/PluginFacebook.h" file not found ios sdkbox

I tried to build my game on ios and integrated facebook through sdkbox but getting this error while building , “‘PluginFacebook/PluginFacebook.h’ file not found”. Its coming in line "#include “PluginFacebook/PluginFacebook.h” in “PluginFacebookJSHelper.cpp” . Any idea what I am missing here. cocos creator version is 2.3.4. If anything else is required from my side then do let me know.

PluginFacebook.h is in PluginFacebook.framework, plz check if PlguinFacebook.framework is exist and included in your xcode project.

here is a fb sample for creator. maybe you can take a look:
