Not terribly helpful since the cocoa headers are what they are, but in other codebases I sneak around issue this by setting up the defines:
#define FALSE 0
#define TRUE (!FALSE)
Then something like "if (mybool == TRUE)" acts as expected across all non-zero values.
Also, IIRC, static analysis tools can enforce all boolean expressions in your code is a bolean logical operator or resolves to a 'typedef int mybool_t', but I'm less than convinced of the usefulness of this.
