In which line are you getting the error and what is the exact error? Have you added the UIAlertViewDelegate protocol in the interface declaration? It seems that you have not.

And you don't need to release alertView in delegate method. You can just release it after showing.

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"That's it" message:@"THANKS FOR USING" delegate:self cancelButtonTitle:@"bye" otherButtonTitles:nil];
[alert show];
[alert release];
