-(void)awakeFromNib{
  [super awakeFromNib];
  for(NSLayoutConstraint *cellConstraint in self.constraints){
    [self removeConstraint:cellConstraint];
    id firstItem = cellConstraint.firstItem == self ? self.contentView : cellConstraint.firstItem;
    id seccondItem = cellConstraint.secondItem == self ? self.contentView : cellConstraint.secondItem;
    NSLayoutConstraint* contentViewConstraint =
    [NSLayoutConstraint constraintWithItem:firstItem
                                 attribute:cellConstraint.firstAttribute
