NSPredicateEditor

I'm using the NSPredicateEditor template in IB, and it works well. 
The exception is with a BOOL value.  For example, if I have a BOOL 
value called flag, and I want to use the string (flag == 1), however, 
using the NSPredicateEditor always produces the string (flag == "1") 
which doesn't work.  Is there an option to create the string without 
the quotes?  Or is there some setting in NSPredicateEditor I'm not 
aware of?
TIA.
