When used in table view with sections and section headers UITableViewCell contentView gets 0.5 point cut off from the bottom.
So if cell height is 80.0 points the contentView will be 79.5 points. The button height will be 80.0 and the bottom 0.5 points will be visible after swiping back.
To fix it button should take it's frame height from contentView.frame rather that from view.frame.
