Bind NSTableColumn to NSArrayController programmatically

Question

How can i bind a NSTableViewColumn to an NSArrayController programmatically? i have a table with 2 columns that are already bound to the array controller. but i am adding new columns at Runtime, and these need to be bound to the arrangedObjects of the arraycontroller. its a cellbased NSTableview. I only found this code online but am not able to make it work..

 NSString *akey = @"somekey";
 NSString *keypath = [NSString stringWithFormat:@"arrangedObjects.%@",akey];
 [newColumn bind:@"value" toObject:arrayController withKeyPath:keypath options:nil];

i am not sure about the "bind:" part and did not understand the apple documentation, that says that i have to expose a binding..

Any help appreciated.

thanks

用NSValueBinding替换“值”应该工作
