Question

Which one of these will produce the most efficient/smaller binary code?

THIS

int sum = 0;
for (NSNumber * oneObj in objArray) {
    if ([oneObj intValue] > 10)
        sum += [oneObj intValue];
    else
        sum -= [oneObj intValue];
}

OR THIS?

int sum = 0;
for (NSNumber * oneObj in objArray) {
    sum += ([oneObj intValue] > 10) ? oneObj : -oneObj;
}

does it make any difference writing the IF in this condensed form?

Answer 1

The compiled versions will be identical.

It’s two different ways of expressing the same thing
