Issues with UITableViewCell contenView width on iPad

I've a UITableViewCell with custom headerView, footerView and ContentView. On iPhone (devices & simulator) renders fine开发者_如何转开发, and the width of contentView adjust to the cell perfectly. But on iPad (booth device / simulator) the contentView is smaller than the UITableViewCell and shows a left and right margins. HeaderView and footerView adjust right to screen and UITableViewCell, only the contentView has this issue,

how can I resize the contentView to adjust equal than header and footer view? I've tried with autoresizing mask for flexible width without any result...

Thanks in advance,

Have you tried setting the frame of the contentView to the width of the UITableViewCell manually?

contentView.frame = CGRectMake(0, 0, cell.frame.size.width, contentView.frame.size.height);
