Objective-C - How to get sum of Boleans?

Question

Through the code below, I can get an output such as :
0
1
1

What I want is to output the sum of these boolea

Answer 1

int sum = (test3 ? 1 : 0) + (testX ? 1 : 0) + (testY ? 1 : 0);

And not so weird variant:

#define BOOL_TO_INT(val) ((val) ? 1 : 0)

int sum = BOOL_TO_INT(test3) + BOOL_TO_INT(testX) + BOOL_TO_INT(testY);
