Thank you Roland.
Actually, I tried that function...but there is a problem that I can't
figure out.
the following is my code segment...
ABAddressBookRef addressBook=ABAddressBookCreate();
CFArrayRef grpval= ABAddressBookCopyArrayOfAllGroups(addressBook);
CFIndex groupCount = ABAd

On initial read, I didn't quite follow this. If my method is returning a foo

I know you guys probably know this, but to be technically accurate,
there is no guarantee the return value of stringByAppendingString
returns an autoreleased string.
While your point is true, it's not actually a rebuttal - you can
assume objects returned from such methods are autoreleased,

You can configure this in IB. Put IB in the list-view mode (click the
center button of the 3-part button in the upper-left of the project
window). Find and select your table view in the list, and uncheck
'Reordering' and perhaps 'Column' in the inspector.
