Tableview edits


I have a coreData app w/8 columns …the user ‘edits’ 5 columns and I want to perform some basic arithmetic using these entries and enter the result in the remaining column…is this possible w/cocoa/coredata/doc based app…pretty basic spreadsheet stuff but I cannot find a hint anywhere …


I don’t think that this is relevant to Chapter 11 of the book in question.

  1. Yes it is possible
  2. Find out how by getting the book on amazon:
  3. By the time you reach this chapter (1!) you’ll know enough to create a basic table arithmetic app.

Please keep your questions in context.
