Hi. I'm a Cocoa newbie, and I'm trying to figure out how to enable sorting columns of my table, but the NSTableView guide doesn't say anything about it. I see that NSTableView has a setSortDescriptors method, NSTableColumn has a setSortDescriptorPrototype method, and that IB shows a "sort key" attribute for a table column, but I'm not clear on how to use them. Any hints or examples?


I'm sure Vijay's solution is more correct than mine, but I implement the

-(void)tableView:(NSTableView *)tableView didClickTableColumn: (NSTableColumn *)tableColumn

delegate method and highlight the column header myself (reversing the sort as necessary and setting the right sort direction indicator). Then I sort my data source and call reloadData on the table object.

I found this MacTech article useful for getting to know NSTableView a little better also:
