I have 3 NSMutableDictionaries that hold data for 3 separate UITableViews. When a value is checked from one of the UITableViews, I want to hold that value so depending on the different values that are checked from the different tables, I can generate an answer on the next page. I thought maybe I could create a new NSMutableDictionary that has all the possible selections, and then when a user hits the checkbox, to tell my newNSMutableDictionary that that value has been selected. But I don’t think it works that way since it’s a key-value-pairing. I was wondering if there were alternatives to this, or if someone had a good way of holding this information? Thanks.

    why not store all possible selections in a NSDictionary, initialise it with the all the selections a user can make. When the user makes a selection add that item to a “selectedItems” NSMutableDictionary. This way your NSMutableDictionary (that contains selections) will only ever have the selected items in it, you can then add and remove from this dictionary without needing to mutate the non-mutable NSDictionary that contains the selections that a user can make..?
