ios - How to use NSPredicate with Multidimensional array (where the predicateFormat exists at valueForKeyPath) -

-

i have array 'id' on want filter array exists @ valueforkeypath 'objectid' of each of dictionaries. how compare predicates in valueforkeypath.

currently.. predicate 

nspredicate * objidpredicate = [nspredicate predicatewithformat:@"objectid = %@",obj]; nsarray * oneorder = [array filteredarrayusingpredicate:objidpredicate];

is considering key , values of array elements, not ones @ valueforkeypath=@"objectid"

use "self"in code array element's valueforkeypath

nspredicate *objidpredicate =[nspredicate predicatewithformat:@"(self.objectid = %@)",obj];
