<PRE>Hello,
|
||
|
|
|
||
|
|
><i> I ran into a usage pattern that seems common.  In Interface Builder define
|
||
|
|
</I>><i> an NSTableView and an NSArrayController.  Set the NSArrayController as the
|
||
|
|
</I>><i> outlet for the NSTableView's dataSource and delegate.  Then specify the
|
||
|
|
</I>><i> NSArrayController to be a custom class.
|
||
|
|
</I>
|
||
|
|
So I was looking into this, and the recommended use case for the
|
||
|
|
NSArrayController is not to set it as the delegate/data source as you
|
||
|
|
described, but instead to use Bindings (KVO/KVC) to hook up the data,
|
||
|
|
and this would require no intervention on your end for this, nor
|
||
|
|
implementing the protocols like that.
