objective-c fetching array elements?

Question

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?

Answer 1

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

Answer 2

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

Answer 3

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