UITableViewCell and Centering an Image

This is one of those code snippets that took me a while to find on the net so I thought I would put it here so maybe someone else might come across it without too much difficulty.  Its just one of those weird iOS development problems.

How to center a UIImageView within a custom cell?

    UIImageView *pic = [[UIImageView alloc] initWithImage:[arr objectAtIndex:indexPath.row]]; 

    pic.center = CGPointMake(cell.contentView.bounds.size.width / 2 , 60);

    pic.contentMode = UIViewContentModeScaleAspectFit;

    cell.selectionStyle = UITableViewCellSelectionStyleGray;

    [cell.contentView addSubview:pic];

 [arr objectAtIndex:indexPath.row]] is just an array holding my images.  It could be any image here.
