UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 100, 300, 100)];

    label.numberOfLines = 3;

    NSMutableAttributedString *content = [[NSMutableAttributedString alloc]initWithString:[NSString stringWithFormat:@"您的待辦業務條fasdfasdfosadfjasdkljfklasjklfjasdlkjfklasdjklfjalskdjflkadsj"]];

    NSRange contentRange = {0,[content length]};

    [content addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:NSUnderlineStyleSingle] range:contentRange];

    label.attributedText = content;

    [self.view addSubview:label];

                [str addAttribute:NSFontAttributeName value: kFontSize_24 range:NSMakeRange(0, 2)];

                [str addAttribute:NSFontAttributeName value: kFontSize_100 range:NSMakeRange(2, str.length - 4)];
