  Are you sure you have the capitals right...? In Objective C you would usually use BOOL with the values YES and NO representing 1 and 0, or true and false - see here:

  I don't know much about this, but the most common confusion over Booleans in Objective C seems to be that BOOL is implemented as a "signed char" data type (meaning that it can take other values apart from 1 and 0) unlike "_Bool" which can only store 1 or 0.
