Fires EXC_BAD_ACCESS

Hi I am trying to implement Captcha functionality. The following code, i have used for generating random word:

-(void) createCaptchaWord{
        lettersArray = [[NSMutableArray alloc] initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z", nil];
        randomWord = @"";

    for(NSUInteger i=0;i<5;i++){
        NSUInteger randomNumber = arc4random()%[lettersArray count];
        randomWord = [randomWord stringByAppendingString:[lettersArray objectAtIndex:randomNumber]];
        //randomWord = [NSString stringWithFormat:@"%@%@",randomWord,[lettersArray objectAtIndex:randomNumber]];
    }

    NSString *captchaUrl = [NSString stringWithFormat:@"%@%@",CommonFunctions.captchaImgUrl,randomWord];
    UIImage *captchaImage = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:captchaUrl]]];

    [captchaImgView setImage:captchaImage];
}

The problem is with the variable randomWord. I can access this variable inside the method named "createCaptchaWord". There is another function to save all the information entered. In that method, when i tried to access the variable "randomWord", I got the exception EXC_BAD_ACCESS. Then i enabled NSZombie. Thus i got the following message in the console:

-[CFString respondsToSelector:]: message sent to deallocated instance 0x4656c10

Can anyone help me to solve this issue.

Regards, Sreelash

You have to retain the value which will be assigned to the randomWord variable with either using retain or a setter method (when it's a property) like self.randomWord = ...
