swift UITableView 隐藏分组的footer, 自定义footer

1.设置高度为0
tv.sectionFooterHeight = 0

2 代理footview 返回 nil

    func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {

      return nil

    }

    func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {

     return 0

    }

自定义footer 

背景view 设置frame, subviews 使用约束布局

    
    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        if section == 1 {
            let bgView = TGSUIModel.createView(bgColor: TGSUIModel.createColorHexInt(0xEEF0F3))
            bgView.frame = CGRect(x: 0, y: 0,  TGSScreenWidth, height: 30)
            let titleLable = TGSUIModel.creatLabe(text: "其他登录方式", font: TGSFontTool.getPingFangFont(14), textColor: TGSUIModel.createColorHexInt(0x666666), textAlignment: .left)
            bgView.addSubview(titleLable)
            titleLable.snp.makeConstraints { (make) in
                make.left.top.equalTo(15)
            }
            return bgView
        }
        return TGSUIModel.createView(bgColor: TGSUIModel.createColorHexInt(0xEEF0F3))
    }
