Delete confirmation moves images in UITableViewCell, but nothing else

I have a subclassed UITableViewCell that adds an image to the contentView, as well as two custom UILabels. When the table goes into editing mode everything shifts to the right correctly, but if I click on the delete control it nudges the frame of the image (which uses its own variable 'thumbnail') to the left. The labels stay in place, even though they're also subviews of contentView - so the image frame is being redrawn and contentView and the label frames are not.

I've tried overriding layoutSubviews but that doesn't seem to help, or I'm not doing it in the right way.

Does anyone know how to ensure contentView is treated as a single object, and prevent its individual subviews being moved? I'm not using IB and would prefer to keep it th开发者_JAVA百科at way.

Thanks!
