Question

I want to be able to random a value when a UIButton is pressed.

I tried if else statement but it seems to be crashing.

Answer 1

Try this:

[ButtonName addTarget:self action:@selector(randomize) forControlEvents:UIControlEventTouchUpInside];

- (void) randomize
{

    random = arc4random()%5;

    switch (random)
    {
        case 0:
                *condition*
             break;
        case 1:
                *condition*
             break;

.....

}

hope this could help you.
