OK,
So the project previously worked in PB, did you create it and have
you changed it during the upgrade to XCode?
I ask because the data source must have been set previously, and
connections don't 'just break'.
I suppose I'm making a fair assumption that your table view isn't
being filled with data when you run the app...
The connection could have been made in code, but assuming you haven't
changed anything...
There could be a line like this:
[myTableView setDataSource:self];
this would be in the class containing the objectValueForTableColumn
implementation, therefore self is an instance of your data source.
where myTableView comes from I'll ignore for the time being...
or the link could have been made entirely in Interface Builder, this
is done by control dragging a connection from the table view to the
instance of your data source and selecting 'dataSource' in the
inspector.
If none of this makes sense you will need to go over some of Apples
tutorials or buy a nice Cocoa book.
I don't know of any setting in XCode which could prevent any of this
(specifically) from working, if there is I would like to know.
Hope your getting closer (if not you could supply the project and
I'll have a browse).

Thanks for your help and suggestion.I have gone through the above
document previously,but it is not clear as how the function
objectvaluefortablecolumn gets called.
objectValueForTableColumn is an NSTableView data source method, not
sure exactly what you mean by 'under the Tableview'.
Under the TableView I meant as how do you make sure the function
under the object NSTableView is getting called.I tried to debug the
application.But when I put the break point inside this function it
never gets called.There I am really confused.
objectValueForTableColumn is called by the table view when it
requires new data from the data source
I would like to add further is that the project I am working on
is preoviously build on project builder.
Did it work then?
If so it sounds like the link between the table view and the data
source may have broken somehow...
Yes it was working then.Can you help me as how to recreate the link
between table view and the data source.
