UiTableViewCell 为表格视图中的每个部分单选复选标记

UiTableViewCell single selected checkmark for each section in the tableview

如何使用自定义单元格对每个部分进行复选标记单选,当我意识到这段代码时,单元格没有标记

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        guard let it = PayMentSection(rawValue: indexPath.section) else {return}
        switch it {
        case .delivering:
            let cell = tableView.dequeueReusableCell(withIdentifier: cellid) as! MakePaymentTableViewCell
            cell.checkBox.isChecked = true
            cell.accessoryType = .checkmark
        case .ordering:
            let cell2 = tableView.dequeueReusableCell(withIdentifier: cellid2) as! MakePaymentTableViewCell2
            cell2.checkBox.isChecked = true

        }

    }

    func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
        guard let it = PayMentSection(rawValue: indexPath.section) else {return}
        switch it {
        case .delivering:
            let cell = tableView.dequeueReusableCell(withIdentifier: cellid) as! MakePaymentTableViewCell
          cell.checkBox.isChecked = false
            cell.accessoryType = .none
        case .ordering:
            let cell2 = tableView.dequeueReusableCell(withIdentifier: cellid2) as! MakePaymentTableViewCell2
          cell2.checkBox.isChecked = false

            cell2.accessoryType = .none
        }
    }

首先,像这样实现UITableViewDelegate'stableView(_:willSelectRowAt:)方法,

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
    if let selectedIndexPathsInSection = tableView.indexPathsForSelectedRows?.filter({ [=10=].section == indexPath.section }), !selectedIndexPathsInSection.isEmpty {
        selectedIndexPathsInSection.forEach({ tableView.deselectRow(at: [=10=], animated: false) })
    }
    return indexPath
}

接下来,在 MakePaymentTableViewCellMakePaymentTableViewCell2 单元格中,覆盖 setSelected(_:animated:) 方法,即

class MakePaymentTableViewCell: UITableViewCell {
    //rest of the code...
    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
        self.accessoryType = selected ? .checkmark : .none
        self.checkBox.isChecked = selected
    }
}

无需实施 didSelectRowAtdidDeselectRowAt 方法。
