I did:
[ myArrayController addObserver: self
forKeyPath: @"arrangedObjects"
options: 0
context: NULL
];
But editing some value in some row does NOT trigger this.
Works fine when I observe "selectionIndexes" instead.
But I need to know when the content of the arrangedObjects (some value in some
MutableDictionary) has changed.
TableView has textDidEndEditing, but this is deprecated.
The delegate has ...shouldEditTableColumn... but I need ...didEdit...
The table is cell-based.
What else to try?
Gerriet.
