UITableView滚出屏幕时清除单元格值

我有从 nib 文件创建的表视图单元格。表格视图中有不同的单元格，要通过键盘获取输入，我必须在屏幕上滚动表格视图。现在的问题是，当我这样做时，我的单元格值被清除。

我知道当视图关闭并出现在屏幕上时，会重新创建单元格，但更糟糕的是，此时我的用户默认变量为空，并且我得到空文本字段。

为了确认该值仍然是用户默认值，当我重新加载应用程序时，该值会回来。

这就是我创建 tableviewcell 的方式，

else if ([indexPath row] == 4)
{
    static NSString *WeeklyHoursCellIdentifier = @"WeeklyHoursCell";

    WeeklyHourTableViewCell *tempTextfieldcell = (WeeklyHourTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:WeeklyHoursCellIdentifier];
        if (tempTextfieldcell == nil) {
            [[NSBundle mainBundle] loadNibNamed:@"WeeklyHourTableViewCell" owner:self options:nil];
            tempTextfieldcell = calculateTextFieldTableViewCell;
            self.calculateTextFieldTableViewCell = nil;
    }


    if ([prefs objectForKey:@"iPhoneWeeklyHours"] != nil) {
            tempTextfieldcell.textField.text = [prefs objectForKey:@"iPhoneWeeklyHours"];

        }

大家有什么想法吗？我真的被困在这里了。

谢谢

I have table view cell created from a nib file. There are different cells within tableview and to get input via keyboard I have to scroll tableview up the screen. Now problem is when I do that my cell value is cleared.

I know that cell is recreated when view goes off and on the screen but even worse is that my user defaults variable is null at that point and I get empty textfield.

To confirm the value is still in the user defaults, when I reload the application that value comes back.

This is how I am creating my tableviewcell

else if ([indexPath row] == 4)
{
    static NSString *WeeklyHoursCellIdentifier = @"WeeklyHoursCell";

    WeeklyHourTableViewCell *tempTextfieldcell = (WeeklyHourTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:WeeklyHoursCellIdentifier];
        if (tempTextfieldcell == nil) {
            [[NSBundle mainBundle] loadNibNamed:@"WeeklyHourTableViewCell" owner:self options:nil];
            tempTextfieldcell = calculateTextFieldTableViewCell;
            self.calculateTextFieldTableViewCell = nil;
    }


    if ([prefs objectForKey:@"iPhoneWeeklyHours"] != nil) {
            tempTextfieldcell.textField.text = [prefs objectForKey:@"iPhoneWeeklyHours"];

        }

Any idea guys. I am really stuck here.

Thanks
