I have a table view whose delegate's -

this dictionary to display to the user):
xkDateModified = 2008-01-15 23:03:00 -0800;
xkDisplayStatus = "Awaiting Pickup";
xkFileName = "stuff.graffle";
xkOwnerID = "lala@xxxxxxxxxxxx";
I'd like to make the "File Name" columns sortable, so I've set up
the file name column's sort key to be xkFileName and the selector to
be compare:. The sorting triangle appears in the header, but the
column isn't being sorted.
I have verified using an NSLog() inside of -
tableView:objectForTableColumn:row: that [resultObjectValue
valueForKeyPath:@"xkFileName"] returns the proper file names.
What am I doing wrong?
Nothing! You have to just sort your model array in the controller
- (void)tableView:(NSTableView *)tableView sortDescriptorsDidChange:
(NSArray *)oldDescriptors AVAILABLE_MAC_OS_X_VERSION_10_3_AND_LATER;
