title: Save NSDictionary to plist
body: <p>I am using the code found in this post: <a href="https://stackoverflow.com/questions/6192451/mulitple-arrays-from-plist/6193397#6193397">Mulitple Arrays From Plist</a>, with the same plist formatting.</p>
  
  <p>This works successfully, however I do not know how to save the created arrays back into a plist, in the same format.</p>
  
  <p>How would I achieve this?</p>
  
  <p>EDIT: It is not so much the saving that I need, but the forming of the data to save.<br>
  The plist is an array of dictionaries with strings and their corresponding keys.
  All the strings with a certain key are put into an array of their own.</p>
  
  <p>How would I put that array back into the correct positions in the array of dictionaries, ready to save?</p>
