title: Read and write specific cells of an iWork Numbers file stored in iCloud
body: <p>This is the scenario, I have three iWork Numbers files, created with the latest Mavericks version and saved on iCloud:</p>
  
  <p>timesheet_2014.numbers where I am gathering all the working hours
  invoice_model.numbers the model for my invoice
  invoice_register.numbers where I am keeping track of all my due and paid invoices</p>
  
  <p>At the end of the month I am taking figures from the timesheet, preparing an invoice manually, and store its reference in the register.</p>
  
  <p>I am doing all this manually and I am trying to automate the whole process. 
  At the moment I do not want to write a full program, but my preferred choice would be to prepare some sort of objective-c script with this behaviour:</p>
  
  <ol>
  <li>read a given table and cell from the timesheet</li>
  <li>Load the model, duplicate it and fill relevant cell with given values</li>
  <li>Lookup register for the latest progressive invoice number and assign +1 to the current invoice</li>
  <li>Save invoice in PDF (google drive or dropbox storage) and store the reference (just invoice number, due date, ecc..) in register</li>
  </ol>
  
  <p>After the introduction, these are the questions:</p>
  
  <ol>
  <li>Has objective-c a set of specific API for dealing with iWork files ?</li>
  <li>How can I load Numbers file from the native iCloud storage ?</li>
  <li>I know the answer would be NO, nut I am asking the question in case something has changed with iOS 7: the script would be normally launched from a Mac, but is there any chance I can run from an iOS device with an iOS app ? The app would needs to have access to files on iCloud.</li>
  <li>Is there a valid alternative to Objective-c ? Preferrably something built-in in Mavericks.</li>
  </ol>
