Is it possible to bind multiple controls to filter one NSArrayController?

I have one table view that should be filtered by values of search field and by element of dropdown list simultaneously. Currently I've binded search field to array controller and it works as it should. But I have no idea how to add constrains from another control - drop down list so it wouldn't reset array filtered by search but filter its current results.

Solution

  • I still do not know if it is possible.

    So i've chose another way to solve my problem.

    1. Create an outlet to NSArrayController
    2. Subscribe to notifications from controls. (NSControlTextDidChangeNotification and NSComboBoxSelectionDidChangeNotification)
    3. Use setFilterPredicate to set new programmatically created predicate for my NSArraycontroller.

    Works as expected and almost no bindings used.
