objective-c fetching array elements?

this line of code gives the ans. 2 (which is right)

int def = arc4random() % 2;
NSLog(@"%@",[uniqueNumbers objectAtIndex:def]);

but when i use

int def = arc4random() % 2;
//NSLog(@"%@",[uniqueNumbers objectAtIndex:def]);
c1 = (int)[uniqueNumbers objectAtIndex:def];
NSLog(@"%d", c1);

it gives 115669616. where c1 is an integer. what is the problem?

Try c1 = [[uniqueNumbers objectAtIndex:def] intValue];.

NSArray holds objects, not integers. that cast to int is not valid.

You get an NSNumber instance back. You need to unbox it by calling intValue on it, then you'll be good to go.
