I have two NSArrayControllers and and NSTableColumn. Depending on
some other factors (what is selected in another table), I want to
change which of the controllers is shown in the table. So far I'm
doing this by changing the bindings of the table column. That works
fine, but it is a little messy, because there are actually also other
UI elements that need to be changed accordingly (add and remove
buttons for the table, textfields that display details of the table
selection, ...). I currently have to change bindings for five
different UI elements each time.
Here is my question: can I somehow always have the table column (and
all the other UI elements) be bound to the same array controller, and
simply change the content of that controller? My naive approach (that
didn't work) was this:
- the app delegate exposes a controller "combinedResourceController"
- in IB, I bind the table colum to that controller like so:
appDelegate.combinedResourceController.arrangedObjects.anyLabel
- in the app delegate, I let the combinedResourceController var point
to either of the two resource controllers, depending on the
situation. E.g.:
Is this a step in the right direction? If so, what is missing to make
this work (so far, nothing shows up in the UI)? If not, what should I
do instead. Basically, I would like to reduce the amount of code and
manual binding to a minimum.
Cheers,
Knud
