Subject: NSTableColumn's sort key in Interface Builder
I have a table view whose delegate's -
tableView:objectValueForTableColumn:row: returns an NSDictionary with
key value pairs that look like this for each of its columns (the
columns' cells are responsible for extracting some subset of 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?
