It actually works with view-based NSTableViews. I'm not using NSArrayController
but implement
- (NSView *)tableView:(NSTableView *)aTableView
viewForTableColumn:(NSTableColumn *)tableColumn
row:(NSInteger)row
where I use this code:
NSTableCellView *result;
result = [aTableView makeViewWithIdentifier:@"entriesCellView" owner:self];
result.objectValue = [self.entryController entryForRow:row];
result.toolTip = @"Any ToolTip String here";
This should also work with bindings.
