ios – 函数中缺少返回预期返回’UITableViewCell’,但实际返回两次

我正在尝试设置一个表视图,它将根据顶部的分段控制器更改单元格.但是,在重新加载tableview时尝试更改单元格时,我收到了返回函数错误,而实际上我有一个返回函数.我该怎么做才能解决这个问题？

func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {




    if friendSELEctor.SELEctedSegmenTindex == 0 {
        print("0")

        cell = self.friendsTable.dequeueReusableCell(withIdentifier: "cell",for: indexPath) as! FriendsTableViewCell


        cell.nameLabel.text = friends[indexPath.row]
        cell.BACLabel.text = String(friendsBAC[indexPath.row])
        cell.statusImageView.image = friendsImage[indexPath.row]

        return cell

    }

    if friendSELEctor.SELEctedSegmenTindex == 1 {
        print("1")

        celladd = self.friendsTable.dequeueReusableCell(withIdentifier: "celladd",for: indexPath) as! FriendsAddTableViewCell

        celladd.nameLabel.text = requested[indexPath.row]
        celladd.statusImageView.image = UIImage(named: "greenlight")

        return celladd


    }

}

func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if friendSELEctor.SELEctedSegmenTindex == 0 {
        print("0")

        cell = self.friendsTable.dequeueReusableCell(withIdentifier: "cell",for: indexPath) as! FriendsTableViewCell


        cell.nameLabel.text = friends[indexPath.row]
        cell.BACLabel.text = String(friendsBAC[indexPath.row])
        cell.statusImageView.image = friendsImage[indexPath.row]

        return cell

    }

    else {
        print("1")

        celladd = self.friendsTable.dequeueReusableCell(withIdentifier: "celladd",for: indexPath) as! FriendsAddTableViewCell

        celladd.nameLabel.text = requested[indexPath.row]
        celladd.statusImageView.image = UIImage(named: "greenlight")

        return celladd


    }

}
