  <p><strong>CustomeCell.m</strong></p>
  
  <pre><code>-(void)layoutSubviews
  {
      [super layoutSubviews];
  
      _con_view_width.constant = _lbl_property.frame.size.width;
      if(!_btn_imageCount.isHidden)
      _con_view_width.constant = _lbl_property.frame.size.width + _btn_imageCount.frame.size.width;
  
      NSLog(@"%@",NSStringFromCGRect(_view_lbl_btn.frame));
  
      [_view_lbl_btn updateConstraintsIfNeeded];
