/me raises hand.
I'm currently stuck on challenge 1 in chapter 8 (pg 135): Make the
application sort people based on the number of characters in their
names using only Interface Builder.
I can do it by cheating (not using Interface Builder), but for the
life of me I can't figure it out using only IB.
The secret is to stick 'length' on the end of the sortKey, and use
'compare:' as the selector. I.e., 'length' can be treated as a read-
only property of the string, of type NSUInteger.Attachment:
