ios - 如何访问 "cell for row at indexpath"之外的 uitableview 单元格元素

Question

我正在使用具有动态行数的uitableview。 (最多 4 个)。我正在手动进行本地化。因此，当有一个单元格时，定位效果非常好。但是当有多个单元格时，我的应用程序就会崩溃。这是我的代码

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell : customerCell = tableView.dequeueReusableCellWithIdentifier("customerCell") as! customerCell
    func localcell()
    {
        cell.lblpassegernumber.text = Localization("Passanger1")
        cell.lblSeatNo.text = Localization("SeatNo")
        cell.lblTCnumberL.text = Localization("TcNumber")
        cell.lbltelephonenoL.text = Localization("MobileNumer")
        cell.lblnameL.text = Localization("NameSurname")
        cell.lblemailL.text = Localization("EMailAddress")
    }

    if (indexPath.row == 1)
    {
        localcell()
        email1      = txtemailaddress.text
        telephone1  = txtnameSurname.text
        tcnumber1   = txtTCnumber.text
        name1       = txtnameSurname.text
    }
    if (indexPath.row == 2)
    {
        localcell()
        email2 = txtemailaddress.text!
        telephone2  = txtnameSurname.text
        tcnumber2   = txtTCnumber.text
        name2       = txtnameSurname.text
    }
    if (indexPath.row == 3)
    {
        localcell()
        email3 = txtemailaddress.text!
        telephone3  = txtnameSurname.text
        tcnumber3   = txtTCnumber.text
        name3       = txtnameSurname.text
    }
    if (indexPath.row == 4)
    {
        localcell()
        email4 = txtemailaddress.text!
        telephone4  = txtnameSurname.text
        tcnumber4   = txtTCnumber.text
        name4       = txtnameSurname.text
    }
    return cell
}

我哪里出错了。并且请建议我是否有任何其他选项可以访问索引路径行的侧单元格外的 uitableviewcell 元素

您可以在 Storyboard中创建 1 个原型(prototype)单元。在 TableView Controller 中这样做

 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return dynamicnum.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

   let cell : customerCell = tableView.dequeueReusableCellWithIdentifier("customerCell") as! customerCell

    cell.lblpassegernumber.text = Localization("Passanger1")
    cell.lblSeatNo.text = Localization("SeatNo")
    cell.lblTCnumberL.text = Localization("TcNumber")
    cell.lbltelephonenoL.text = Localization("MobileNumer")
    cell.lblnameL.text = Localization("NameSurname")
    cell.lblemailL.text = Localization("EMailAddress")

    return cell

}
