title: Updating iOS resource files remotely
body: <p>I have an app on the App Store that needs to have its resource data files updated periodically (every 2-3 months).  So far, I've just been deploying a new version of the app to the App Store every time I need to do this, but the fact that I have to wait a week or two for the changes to become live is cumbersome.</p>
  
  <p>Theoretically, I was thinking of creating a new "version_control.txt" resource file which tracks the version numbers of every other resource file.  Periodically, the app would check its version_control.txt against a version up on some web server, and then download any files that need to be updated.</p>
  
  <p>Do there exist any frameworks or SDKs to handle all of this for me, or do I have to write everything myself?  Is there a better solution?</p>
