You have to do Type casting Nsnumber to int.For converting you can use IntValue metod.for knowing more about Foundation Data Type use apple s documents.

-objectAtIndex: returns an object — in your case, an instance of NSNumber. To convert it to int, use the -intValue method. For instance, replace

int p=[array objectAtIndex:counter];

with

int p=[[array objectAtIndex:counter] intValue];
