Hi,

I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working.

- (IBAction)generateNewJoke {
if (i < [jokeArray count]) {
    i++;
        [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex];

    int oldnumber = [userDefaults integerForKey:kOldIndex];
    int newnumber = [userDefaults integerForKey:kNewIndex];

    [answerLabel setText:@""];
    [userDefaults setInteger:i forKey:kNewIndex]; 

    if (oldnumber == newnumber) {
        NSLog(@"they are the same");
        [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; 
    }

    [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]];

}
}
