Answer 1

I think, You can write a loop for that. Please check the following code,

for (int i = 0; i < putNumberUsed.count; i++) {
    int randomInt1 = arc4random() % [putNumberUsed count];
    int randomInt2 = arc4random() % [putNumberUsed count];
    [putNumberUsed exchangeObjectAtIndex:randomInt1 withObjectAtIndex:randomInt2];
}

I this this may be useful to you.
