objective c - retrieving number from array that can be manipulated -


i trying retrieve number stored in array can manipulate @ later stage.

for example have sum in array i.e. 500 , divide number x.

how accomplished?

so far have , doesn't work:

nserror *error; nsarray *level4results = [context executefetchrequest:request error:&error]; nslog(@"%@", level4results);//check sum value of array  int l4sum = ((int)[level4results indexofobject:0]) / 7; nslog(@"%d", l4sum); //check if l4sum gets values passed 

the output was:

      2013-05-19 18:50:49.648 bla.v1[6254:c07] (         {         sumvalue = 633;     } ) 2013-05-19 18:50:49.650 bla.v1[6254:c07] 306783378 

did try using [level4results objectatindex:0] instead of [level4results indexofobject:0] ?
