However, if I get reference of an item in existing view and insert
new item in its data source, NSMutableArray, it can't display the
newly added nested items.
I tried NSTreeController's rearragneObjects and the NSOutlineView's
reloadItem:reloadChildren, but it doesn't seem to work for me.
Can anyone tell me how to add new items?
Since you’re using NSTreeController, you should modify the array in a
KVO-compatible way. Take a look at
