ios - filtering two arrays one is NSArray(Core Data) and the other is NSMutableArray(simple) -

i getting core data in array consists of records , getting locations distance (2.5 km)example have filter 2 arrays distance

this code doing now

locations ...

locafilterarray = [[nsmutablearray alloc]init]; (int l = 0 ; l < dealarray.count; l++) {     deal * deal = (deal *)dealarray[l];     nsarray * locarray = [[deal locationrelation]allobjects];     double minvalue = 10000;     if (locarray.count > 0) {         (int l = 0; l < locarray.count ; l++) {             deallocation * location = (deallocation *)locarray[l];             double latitude = [[location latitude]doublevalue];             double longitude = [[location longitude]doublevalue];             cllocation * cdlocation = [[cllocation alloc]initwithlatitude:latitude longitude:longitude];             cllocation * currlocation = [[cllocation alloc]initwithlatitude:appdelegate.currentlatitude longitude:appdelegate.currentlongitude];             cllocationdistance distance = [currlocation distancefromlocation:cdlotion]/1000;             if (distance < minvalue) {                 minvalue = distance;             }         }     } else {         minvalue = 5;     }     nsstring * value = [nsstring stringwithformat:@"%.1f",minvalue];     [locafilterarray addobject:value]; } nslog(@"%lu",(unsigned long)locafilterarray.count); 

in way getting printed /// 2.5 , 1.2 , 18.3 , 4.5.... this

and core data getting date there no relation between these 2 arrays have filter core data data ascending order in table view

any great appreciations ... :)
