View Based NSTableView Not showing data

I have a view-based TableView that I am adding trivial data. However the view is not populating correctly.

 - (int)numberOfRowsInTableView:(NSTableView *)aTableView {

int rows=2;

return rows;
}

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn  row:(int)rowIndex {

// The return value is typed as (id) because it will return a string in most cases.


NSTableCellView *aTableCellView = [aTableView makeViewWithIdentifier:aTableColumn.identifier owner:self];

if ([aTableColumn.identifier isEqualToString:@"FirstName"]) {
    aTableCellView.textField.stringValue = @"Mike";
}

if ([aTableColumn.identifier isEqualToString:@"LastName"]) {
    [aTableCellView.textField setStringValue:@"Bagger"];
}

return aTableCellView;

}

If you want to use view-based tables (and already have an NSTableCellView subclass defined in Interface Builder), you should instead override and implement the tableView:viewForTableColumn:row: delegate method:

NSTableViewDelegate Protocol Reference

This method should contain the body of your implementation above, populating and returning the NSTableCellView that you've created.

You should just return the value for the column instead of setting it explicitly. So, instead of doing

aTableCellView.textField.stringValue = @"Mike";

you should just write

return @"Mike"

So, your code should look like below:

if ([aTableColumn.identifier isEqualToString:@"FirstName"]) {
    return @"Mike";
}

if ([aTableColumn.identifier isEqualToString:@"LastName"]) {
    return @"Bagger"];
}

return nil;
