Hi all.
Since it is good programming to not access an array's content
through its controller when in the model I'm trying to find a way to
get to the same object selected in the user interface (i.e. the
array controller).
In my view I have the array content sorted by binding it to a sort
descriptor. Thus, the indices of the array and the content of the
array shown in the view differs.
Now, when a certain object is selected in the view I want to do
something to this object by accessing it through the original array.
My first, perhaps foolish, guess would be to use
indexOfObjectIdenticalTo: or indexOfObject: like this:
int indexOfObject = [theOriginalArray indexOfObjectIdenticalTo:
[theArrayController selection]];
but this does not work. Looking in the reference I see that
[theArrayController selection] will return a proxy object. Is this
the reason my code won't work?
Ask the array controller for its' selectedObjects. This returns an
array of the selected objects and is not a proxy object like
selection. Iterate over that array to get the indexes you're
interested in from your original array.
