在TableView上显示标签。滚动TableView时,这会消失

我有一个隐藏标签的TableView,只有当我通过didSelectRow点击单元格时才会出现。

到目前为止一切都很好,当我选择单元格时,会显示橙色标签(如图所示),但是当tableView滚动标签时会出现问题橙色消失并且只有在我更改页面时才会返回...

橙色标签表示朋友请求是否未决,并且由于使用prepareforsegue报告了一个可变数组,因此引用了另一个页面中存在的查询。

你能解释为什么橙色标签会消失吗?当我选择单元格时如何使其保持在TableView上? 标签橙色是“RichiestaInAttesaLabel” 附:我正在使用Parse.com

-(UITableViewCell * )tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath  {

    static NSString *CellIdentifier = @"Cell";

    FFCustomCellUtentiGenerali  *cell =[self.TableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[FFCustomCellUtentiGenerali alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];


    }


if (!isFiltered) {

    PFObject *object = [self.Utenti objectAtIndex:indexPath.row];

    NSString *str = [object objectForKey:FF_USER_NOMECOGNOME];
    cell.NomeCognome.text = str;

    cell.FFFotoProfilo.file = [object objectForKey:FF_USER_FOTOPROFILO];
    cell.FFFotoProfilo.image = [UIImage imageNamed:@"FFNoFotoUSer"];
    [cell.FFFotoProfilo.layer setMasksToBounds:YES];
    [cell.FFFotoProfilo.layer setCornerRadius:30.0f];
    cell.FFFotoProfilo.contentMode = UIViewContentModeScaleAspectFill;
    [cell.FFFotoProfilo loadInBackground];

    [cell.BackgroundReputazioneBlu.layer setMasksToBounds:YES];
    [cell.BackgroundReputazioneBlu.layer setCornerRadius:15.0f];

    [cell.TapAggiungiLabel setHidden:YES];
    [cell.RichiestaInAttesaLabel setHidden:NO];


    if ([self isFriend:user]) {
         [cell.TapAggiungiLabel setHidden:YES];
        [cell.RichiestaInAttesaLabel setHidden:YES];
    }

    else {


        [cell.TapAggiungiLabel setHidden:NO];
        [cell.RichiestaInAttesaLabel setHidden:YES  ];
    }



    if ([self Is_InAttesa:user]) {
        [cell.RichiestaInAttesaLabel setHidden:NO];
        [cell.TapAggiungiLabel setHidden:YES];

    }

    else {
        [cell.RichiestaInAttesaLabel setHidden:YES];

    }

}
//end IsFiltred
else {

if ([self isFriend:user]) {
     [cell.TapAggiungiLabel setHidden:YES];
    [cell.RichiestaInAttesaLabel setHidden:YES];
}

else {


    [cell.TapAggiungiLabel setHidden:NO];
    [cell.RichiestaInAttesaLabel setHidden:YES  ];
}

为什么“cell.RichiestaInAttesaLabel setHidden:YES”在这两种情况下?
