min and max of NSArray without Zeros

Question

I have a NSArray and want to know the maximum and min integers.

I currently use:

int max = [[array valueForKeyPath:@"@max.intValue"] intValue];
int min = [[array valueForKeyPath:@"@min.intValue"] intValue];

but now I want to know the minimum and maximum without the zeros entering (arrays only have positive values)

ex:
array=[3, 6 ,7 , 13, 86, 45, 0]
min=3
max=86

Is there any method to achieve this?

You mean you want a function to return the max integer in your array ? — Basheer_CAD, Feb 20 '14 at 12:15
I can not understand your question .. can you elaborate more ? — iPatel, Feb 20 '14 at 12:16
for maximum I have, I want one that returns this value without counting the zeros — Pedro, Feb 20 '14 at 12:17
do you mean in your case 3 is the min, ignoring 0 which is smaller ? — Basheer_CAD, Feb 20 '14 at 12:18

int xmin = INTMAX_MAX;
for (NSNumber *num in numbers) {
    int x = num.intValue;
    if (x < xmin && x!= 0) xmin = x;
}

For an `int`, use `INT_MAX`. (That reminds me of the code in http://stackoverflow.com/a/15931719/1187415 :-) – Martin R Feb 20 '14 at 12:26
Hey, no fair actually writing code!! (Never mind that it's faster than using KVC and easier to understand.) – Hot Licks Feb 20 '14 at 12:31
Yep, slightly modified to not include zeros =) – Salavat Khanov Feb 20 '14 at 12:32
(And it would make sense to throw in the max as well, rather than continue to use KVC for that.) – Hot Licks Feb 20 '14 at 12:35
