title: How to use platform-specific plugins in Cordova app dev workflow?
body: <p>I'm new to developing apps with Cordova but I've got a lot working well. I just successfully implemented the <a href="https://github.com/phonegap/phonegap-facebook-plugin/issues" rel="noreferrer">'phonegap-facebook-plugin'</a>. 
  However, following the instructions, I put many files (from the facebook SDK and plugin) directly into the /platform/ios/ directory - which means instead of working in the root /www/ directory and building both platforms at once, my code is now less 'flexible' and is platform specific. 
  Is there a better way to do structure my files and/or workflow? Am I missing a step or a trick?</p>
  
  <p>I appreciate any help.</p>
