i have following nsarray has nsdictionary , need order them higher dictionary value goes on top.

i've researched around can not find predicate sort nsdictionary. how achieve objective??

 nsarray* result = @[@{ @"chest":[nsstring stringwithformat:@"%i",[chestr count]]},                       @{@"back":[nsstring stringwithformat:@"%i",[backr count]]},                       @{@"triceps":[nsstring stringwithformat:@"%i",[tricepr count]]},                       @{@"biceps":[nsstring stringwithformat:@"%i",[bicepr count]]},                       @{@"arms-other":[nsstring stringwithformat:@"%i",[armsr count]]},                       @{@"legs":[nsstring stringwithformat:@"%i",[legsr count]]},                       @{@"shoulders":[nsstring stringwithformat:@"%i",[shouldersr count]]},                       @{@"abs":[nsstring stringwithformat:@"%i",[absr count]]},                       @{@"cardio":[nsstring stringwithformat:@"%i",[cardior count]]},                       @{@"fitness":[nsstring stringwithformat:@"%i",[fitnessr count]]}                         ]; 

edit , solution

this how solved problem

nsarray* result = @[@{ @"chest":@"5"},                         @{@"back":@"3"},                         @{@"triceps":@"4"},                         @{@"biceps":@"9"},                         @{@"arms-other":@"1"},                         @{@"legs":@"0"},                         @{@"shoulders":@"2"},                         @{@"abs":@"3"},                         @{@"cardio":@"8"},                         @{@"fitness":@"9"}                         ];      nsarray *sorted = [result sortedarrayusingcomparator:^(id obj1, id obj2){          nsarray *s1k = [obj1 allkeys];         nsinteger s1 = [obj1[[s1k objectatindex:0]] intvalue];         nsarray *s2k = [obj2 allkeys];         nsinteger s2 = [obj2[[s2k objectatindex:0]] intvalue];          if ( s1 > s2) {             return (nscomparisonresult)nsorderedascending;         } else if (s1 < s2) {             return (nscomparisonresult)nsordereddescending;         }          return (nscomparisonresult)nsorderedsame;     }]; 

a dictionary not sorted - definition.

you may convert array. nsdictionary instance method -allvalues may suitable doing so.

then can sort new array using custom sort descriptor ensures sorted in way want be.
