- (unsigned)lineNumber
{
unsigned result = ++_lineNumber; // increment each time we are
asked, which is once per row
if (_lineNumber == [self numberOfRows]) // when at the last row
we ned to reset the line number
_lineNumber = 0;
return result;
}
@end
2. Bind the desired table view's column to its table view's
lineNumber property.
I created a little test project and it works a treat. The project
also shows how to sort numbers in strings numerically (rather then
alphabetically). To find the project take a break here: http://

If this latest code still is offensive do let me know. :-)
This approach doesn't look good to me. You're relying on an
implementation detail that may change in future and it wouldn't
surprise me if there were some circumstances where the approach
above doesn't work.
Fair enough. The latter had occurred to me, but I couldn't think
offhand of an occasion where this would fail. Can you?
As for relying on an implementation detail that may change: do you
mean trusting that the column will get each cell's contents
sequentially starting from the first row? If so, I guess you're
right. Sigh. Not sturdy enough. My bad.
All right then. No more trying to use bindings to get the row number
of a table column. Back to data sources.
Cheers,
António
