Invoking -setSortDescriptors: on the array controller does sort it (or should).
Back on 10.4, it may have been necessary to follow that with a call to -rearrangeObjects.
-[NSArrayController setSortDescriptors:] alone doesn't work for me even on 10.6, but that combined with -[NSArrayController rearrangeObjects] does the trick. That is, I set use setSortDescriptors: once, and use rearrangeObjects whenever I add new items to the table.
Is your array controller bound to its content, or are you setting that programmatically? If it's bound, then it ought to rearrange its objects when they are added. The fact that it doesn't suggests that you aren't updating the property to which it is bound in a KVO-compliant manner.
The table column is bound to the array controller using IB. I was
adding new items using -[NSArrayController addObject:]. What's the
better way?
