How to change the image of a selected cell of a UICollectionView?

Question

I am trying to use this code, but it's not working:

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
printf("Selected View index=%d",indexPath.row);

UICollectionViewCell *cell = [self.collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
cell.selectedBackgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_s.png"]];
//[self.collectionView reloadData];
}

How do I change the UIImage of selected UICollectionViewCell in a UICollectionView ?
