If anyone came here to resolve an error with react-native-fbsdk after installing it using Cocoapods, keep in mind that you have to remove all the other .a files in your Projects build phases and only keep the .a from cocoapods called libPods-WhateverAppName.a.
This is usually caused from running rnpm link and the way rnpm works.
