Better way of using arc4random

I have a random method to create 2 random integers. My concern is that %65-%70 of outputs are same integers like "5-5" "4-4" "3-3".

-(void)random{
NSUInteger randomNumber = arc4random_uniform(5);

    switch (randomNumber) {
        case 0:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            break;

        case 1:
            _tile2.image = [UIImage imageNamed:@"two.png"];
            break;

        case 2:
            _tile2.image = [UIImage imageNamed:@"three.png"];
            break;

        case 3:
            _tile2.image = [UIImage imageNamed:@"four.png"];
            break;

        case 4:
            _tile2.image = [UIImage imageNamed:@"five.png"];
            break;
    }

    NSUInteger randomNumber2 = arc4random_uniform(5);

    switch (randomNumber2) {
        case 0:
            _tile3.image = [UIImage imageNamed:@"one.png"];
            break;

        case 1:
            _tile3.image = [UIImage imageNamed:@"two.png"];
            break;

        case 2:
            _tile3.image = [UIImage imageNamed:@"three.png"];
            break;

        case 3:
            _tile3.image = [UIImage imageNamed:@"four.png"];
            break;

        case 4:
            _tile3.image = [UIImage imageNamed:@"five.png"];
            break;
    }
}

Should i create 25 different case to reach better result?

NSUInteger randomNumber = arc4random_uniform(25);

   switch (randomNumber) {
        case 0:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            _tile3.image = [UIImage imageNamed:@"one.png"];
            break;

        case 1:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            _tile3.image = [UIImage imageNamed:@"two.png"];
            break;

        case 2:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            _tile3.image = [UIImage imageNamed:@"three.png"];
            break;

        case 3:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            _tile3.image = [UIImage imageNamed:@"four.png"];
            break;

        case 4:
            _tile2.image = [UIImage imageNamed:@"one.png"];
            _tile3.image = [UIImage imageNamed:@"five.png"];
            break;

        case 5:
            _tile2.image = [UIImage imageNamed:@"two.png"];
            _tile3.image = [UIImage imageNamed:@"one.png"];
            break;

        ...
    }
}

arc4random_uniform is great for getting one random integer. When i need to get 2 or more random numbers, the outputs are not that great. What is the best way of doing this?
