I want to get the difference between 2 characterSets. For example: I have the following 2 characterSets... NSCharacterSet *aSet = [NSCharacterSet characterSetWithCharactersInString:@"a"]; NSCharacterSet *lowerSet = [NSCharacterSet lowercaseLetterCharacterSet];
The difference between these (aSet - lowerSet = remainder): NSMutableCharacterSet *remainder = [[NSMutableCharacterSet alloc] init]; [remainder formIntersectionWithCharacterSet:aSet]; [remainder formIntersectionWithCharacterSet:[lowerSet invertedSet]]; This works, but when you turn these 2 around, I have a set that doesn't match a thing. How do I get the same result when I switch aSet and lowerSet in the remainder interesection methods?
