ios - 如何更改ios中特定单词的颜色

Question

我搜索了任何特定的词，例如“上帝”。我想更改特定单词的文本颜色应该更改为不同的颜色。我尝试在谷歌上搜索，但我发现特定索引值的特定单词颜色从单词的开头到结尾发生变化 Link这就是我的问题没有解决的原因。

请帮助我并更新我的代码以更改特定单词的文本颜色，即您在图片中看到的框中的单词。

谢谢

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:UYLCellIdentifier forIndexPath:indexPath];
    [self configureCell:cell forRowAtIndexPath:indexPath];
     return cell;
}

- (void)configureCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([cell isKindOfClass:[UYLTextCellSearch class]])
    {
         UYLTextCellSearch *textCell = (UYLTextCellSearch *)cell;

         DataBase *DBContentDetail = [_sourceData objectAtIndex:indexPath.row];

         textCell.lineLabel.text = [NSString stringWithFormat:@"%@",DBContentDetail.dbtext];
        [textCell.lineLabel sizeToFit];
    }
}

NSString *text = @"In the begining God created heaven and earth. God is great.";

NSMutableAttributedString *mutableAttributedString = [[NSMutableAttributedString alloc] initWithString:text];

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"(God)" options:kNilOptions error:nil]; // Matches 'God' case SENSITIVE

NSRange range = NSMakeRange(0 ,text.length);

// Change all words that are equal to 'God' to red color in the attributed string
[regex enumerateMatchesInString:text options:kNilOptions range:range usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {

    NSRange subStringRange = [result rangeAtIndex:0];
    [mutableAttributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:subStringRange];
}];

textCell.lineLabel.attributedText = mutableAttributedString;
