How do I create a property in the user defaults of type boolean?

Internally it seems to use a NSCFBoolean which is an undocumented type. If I make the assumption it is the same as a CFBoolean, and overlooking the oddness of having to fall back to Carbon for such a fundamental thing, the documentation of CFBoolean doesn't seem to provide a documented method for creating one.

You don't... there is only kCFBooleanTrue and kCFBooleanFalse. To assign a value to a boolean, do:


CFBooleanRef thisOneIsTrue = kCFBooleanTrue;
CFBooleanRef thisOneIsFalse = kCFBooleanFalse;

To test for true or false, you can use:

CFBooleanGetValue(theBooleanValue) which returns a Boolean type...
