ios_setup.js

// Copyright 2004-present Facebook. All Rights Reserved.
/*
 A node script to help set up FBSDK frameworks for use with https://github.com/facebook/react-native-fbsdk
 after you have already run `rnpm install react-native-fbsdk`.

 Note that you need to create a Facebook App in https://developers.facebook.com/
 and get the Facebook APP ID and Facebook APP Name in order to set up the Info.plist.

 Usage:
 1. Copy the script into your react native project root
 2. npm i -D plist xcode adm-zip
 3. do 'node ios_setup.js <AppID> <AppName>'.
