are you implementing the delegate method?
- (void)tableView:(NSTableView *)tableView sortDescriptorsDidChange:(NSArray
*)oldDescriptors
{
// the sort descriptors are specified in Interface Builder for the
lastName column and the relationship column
// the both specify the respective keys, and use the compare: method to
do the sorting
// this message is sent to the delegate when the data is sorted by
clicking on one of those column headers
[peopleArray sortUsingDescriptors: [tableView sortDescriptors]];
[tableView reloadData];
}
I’m setting the sort information in Interface Builder on each column,
specifying the key to sort on, and the compare selector (which is compare:
which probably isn’t the best for localized content). I agree that both the
hidden and non-hidden columns should have the same key and compare selector for
both columns.
When you click on one of those table column headers, the delegate is notified.
Now, this does ‘destroy’ the natural sort order. But you can easily copy that
natural order array into a ‘displayed’ array when loaded, and then upon some
action, put a copy of that natural array in the displayed array. The delegate
implementation above would do something like
self.displayArray=[naturalOrderArray sortedArrayUsingDescriptors:[tableview
sortDescriptors]];
Is this helpful? If you’re having sorted issues that need documenting file a
bug and send me the number ASAP. Seriously, ASAP.
