I'm trying to determine the best way to build this for scalability, performance and maintainability.
I have a Source List which at the top contains a "masterArray" of NSDictionary items. Below that I have several "dumbLists" and "smartLists" which are subsets of the items in the masterArray as determined by the user directly or by user-set criteria. As the user selects a list (only one selectable at a time), I need to change the contents of a table to reflect the current list items. I am thinking that I use a single NSArrayController and just change its content array as needed. However, I'd like to be able to badge each list with the quantity of items in that list which means if I edit one of the items, it might fall in or out of one of the smart lists. In this case after each edit I need to rebuild all the lists.... Or maintain a separate array for each list. Also, if an item is deleted, it also needs to be removed from any lists it might be in. What is the best way to do this? My masterArray on disk is actually a Dictionary with ID numbers as the key and Dicts as the value (in the value dict is another key listing the ID) so that individual items can be quickly located for add/remove. Just looking for the best way to (a) maintain a collection of items as well as many collections that are subsets of the main collection and (b) an easy way to locate individual records (which is much easier with dict key/value pairs than with searching through arrays. I hope this is clear. Trygve _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
