Question

Why do I get this as a result to this code?

CODE

ids = 0;
for (NSString *s in golferThreeIconCounter) {
    ids++;
    NSLog(@"%i", ids);
}

It makes absolutely no sense to me why ids goes up 4 times instead of just once…

Answer 1

When you declare an int, you do not add *: it’s not an <id> type. What you have is a pointer to an int; on a 32-bit platform it increments by 4.

int ids = 0;
