In Chap 18, on page 356, the book states that the Homepwner app is saving and loading the itemKey.
I may be overthinking this, but I don’t think the itemKey is necessary just to archive the items. Only the pictures. Is this correct? Because I can’t find anything in Chapter 18 that points to the archiving actually making use of the itemKey.
I understand how the write/retrieving to/from the file system using NSData is using the key.
