how to initialize nsstring with value?

currently im loading my sounds with 

NSString * strName = [NSString stringWithFormat:@"soundpack%ld", (long) (value+1)];

to get a value for each sound.

now i want to pull it out of an array. looks like this:

NSMutableArray * sounds = [NSMutableArray arrayWithObjects: @"soundpack1", @"soundpack2", @"soundpack3", @"soundpack4", @"soundpack5", @"soundpack6", @"soundpack7", @"soundpack8", @"soundpack9", nil];
    NSUInteger count = [sounds count];

    for (NSUInteger i = 0; i < count; ++i) {
        NSInteger nElements = count - i;
        NSInteger n = arc4random_uniform((u_int32_t )nElements) + i;
        [sounds exchangeObjectAtIndex:i withObjectAtIndex:n];
    }
    NSString * strName0 = [sounds objectAtIndex:1];

ok, now i have shuffled the sounds., now i want to initialize like before with an specific value.

something like:

NSString * strName = [sounds objectAtIndex:%ld, (long) (value+1)];

or

NSString * strName = [sounds objectAtIndex:@"%ld", (long) (value+1)];

didn't work. but i don't know, how to do it now...

Try to change this line

NSString * strName = [sounds objectAtIndex:@"%ld", (long) (value+1)];

to

NSString * strName = [sounds objectAtIndex:(long) (value+1)];

Why dont u use the same snippet after shuffling?

NSString * strName = [NSString stringWithFormat:@"soundpack%ld", (long) (value+1)];
