Whenever I integrate my custom add in Adwhirl so my application crashes [adWhirlView replaceBannerViewWith:replacement]; please let me know how to overcome this issue.

 - (void)performEvent:(AdWhirlView *)adWhirlView {
  // replace banner content
  UILabel *replacement = [[UILabel alloc] initWithFrame:kAdWhirlViewDefaultFrame];
  replacement.backgroundColor = [UIColor blackColor];
  replacement.textColor = [UIColor whiteColor];
  replacement.textAlignment = UITextAlignmentCenter;
  replacement.text = [NSString stringWithFormat:@"Event performed, view %x", adWhirlView];
  [adWhirlView replaceBannerViewWith:replacement];
  [replacement release];
}
