テーブルビューセルにラベルを使用しています。セルには属性付きの文字列が割り当てられていますが、選択時に属性付きの文字列のセル テキストが白にならないという問題があります。

それを修正する方法はありますか..？

どんな助けでも大歓迎です。

ここに私のコードを見てください。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    LHSearchViewCell *cell = [LHSearchViewCell cellForTableView:tableView fromNib:_cellNib];

    cell.selectionStyle = UITableViewCellSelectionStyleGray;

    cell.headerLabel.textColor = [UIColor darkGrayColor];
    cell.headerLabel.highlightedTextColor = [UIColor whiteColor];
    cell.headerLabel.font = [UIFont systemFontOfSize:14];

    cell.subLabel.font = [UIFont systemFontOfSize:12];
    cell.subLabel.textColor = [UIColor darkGrayColor];
    cell.subLabel.numberOfLines = 2;
    switch (indexPath.section) {
        case 0:
        {
            UIFont *font = [UIFont systemFontOfSize:14.0];
            NSDictionary *firstAttributes = [NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName,[UIColor darkGrayColor],NSForegroundColorAttributeName,nil];
            UIFont *secondFont = [UIFont systemFontOfSize:10.0];
            NSDictionary *secondAttributes = [NSDictionary dictionaryWithObjectsAndKeys:secondFont,NSFontAttributeName,[UIColor lightGrayColor],NSForegroundColorAttributeName,nil];
            NSString* completeString = [NSString stringWithFormat:@"%@  |  %@",[_libraryPdfArray objectAtIndex:indexPath.row],[_libraryPdfDateArray objectAtIndex:indexPath.row]];
            NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]     initWithString:completeString];
            [attributedString setAttributes:firstAttributes range:[completeString rangeOfString:[_libraryPdfArray objectAtIndex:indexPath.row]]];
            [attributedString setAttributes:secondAttributes range:[completeString rangeOfString:[_libraryPdfDateArray objectAtIndex:indexPath.row]]];            
            cell.headerLabel.attributedText = attributedString;

            cell.subLabel.text = [_libraryPdfSubtitleArray objectAtIndex:indexPath.row];

        }
            break;

        case 1:
        {
            UIFont *font = [UIFont systemFontOfSize:14.0];
            NSDictionary *firstAttributes = [NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName,[UIColor darkGrayColor],NSForegroundColorAttributeName,nil];
            NSString* completeString = [NSString stringWithFormat:@"%@  |  %@",[_ebriefingPdfArray objectAtIndex:indexPath.row],[_ebriefingSecondLabelTextArray objectAtIndex:indexPath.row]];
            NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]     initWithString:completeString];
            [attributedString setAttributes:firstAttributes range:[completeString rangeOfString:[_ebriefingPdfArray objectAtIndex:indexPath.row]]];
            [attributedString setAttributes:firstAttributes range:[completeString rangeOfString:[_ebriefingSubtitleArray objectAtIndex:indexPath.row]]];
            cell.headerLabel.attributedText = attributedString;
            cell.subLabel.text = [_ebriefingSubtitleArray objectAtIndex:indexPath.row];
        }
            break;

        default:
            break;
    }

    return cell;
}

UILabel サブクラス ソリューション

@implementation CustomLabelHighlighted {
    NSAttributedString *savedAttributedString;
}

-(void)setHighlighted:(BOOL)highlighted {
    if(!SYSTEM_VERSION_LESS_THAN(@"6.0")){
        if(highlighted){
            if(!self.attributedText){
                return;
            }

            NSMutableAttributedString *highAttributedString = [self.attributedText mutableCopy];
[highAttributedString addAttribute:NSForegroundColorAttributeName value:[UIColor whiteColor] range:(NSRange){0, [highAttributedString.string length]}];

            // important!
            [super setAttributedText:highAttributedString];
        }
        else{
            if(savedAttributedString){
                self.attributedText = savedAttributedString;
            }
        }
    } else {
        [super setHighlighted:highlighted];
    }
}

- (void)setAttributedText:(NSAttributedString *)attributedText {
    [super setAttributedText:attributedText];
    savedAttributedString = attributedText;
}
