ios - Sort a NSArray of numbers in ascending order but send zeros at the end -

i have simple nsarray, containing nsnumbers.

i sort array in ascending order way :

nssortdescriptor *lowesttohighest = [nssortdescriptor sortdescriptorwithkey:@"self" ascending:yes]; [_scores sortusingdescriptors:[nsarray arraywithobject:lowesttohighest]]; 

my problem is, i'd nsnumbers containing 0 @ end rather @ beginning. here kind of array may have sort (containing empty nsnumbers example):

0 25 12 0 8 0 

my code of course sorts array this:

0 0 0 8 12 25 

what this:

8 12 25 0 0 0 

of course re-order manually removing lines 0 , adding them @ end, i'm looking cleanest solution possible.

sort array using comparator.

nsarray *sortedarray = [array sortedarrayusingcomparator: ^(id obj1, id obj2) {      if ([obj1 integervalue] == 0 && [obj2 integervalue] == 0)     {         return (nscomparisonresult)nsorderedsame;     }     if ([obj1 integervalue] == 0)     {         return (nscomparisonresult)nsordereddescending;                 }     if ([obj2 integervalue] == 0)     {          return (nscomparisonresult)nsorderedascending;     }      if ([obj1 integervalue] > [obj2 integervalue])      {         return (nscomparisonresult)nsordereddescending;     }      if ([obj1 integervalue] < [obj2 integervalue])      {         return (nscomparisonresult)nsorderedascending;     }     return (nscomparisonresult)nsorderedsame; }];
