What makes you think you can? Logically, you shouldn't be
able. I'd
imagine selectedObjects is always going to return an index set; it'd
just be empty with no selection. I did try comparing it to
NSNoSelectionMarker just in case, and that doesn't work.
Perhaps instead of imagining it would be more helpful to read the
documentation. -[NSObjectController selectedObjects] returns the
actual objects.
You also don't seem to understand how bindings work. Even if -
selectedObjects did return an NSIndexPath, it's a KVO-compliant
property and therefore perfectly suitable for binding to.
