How to disable the NSUndoManager in an NSDocument?

I'm using NSDocument but I would like to disable the undo manager.

How can I do it?

Solution

  • - (BOOL)isUndoRegistrationEnabled

    Return Value

    YES if registration is enabled; otherwise, NO.

    and:

    - (void)disableUndoRegistration

    Disables the recording of undo operations, whether by registerUndoWithTarget:selector:object: or by invocation-based undo.
