下面直接上代码了
添加中划线：
UILabel *strikeLabel = [[UILabel alloc]initWithFrame:(CGRectMake(10,10,50,30))]; NSString *textStr =[NSString stringWithFormat:@"%@元"，primeCost]; //中划线 NSDictionary *attribtDic =@{NSStrikethroughStyleAttributeName:[NSNumber numberWithInteger:NSUnderlineStyleSingle]}; NSMutableAttributedString *attribtStr =[[NSMutableAttributedString alloc]initWithString:textStr attributes:attribtDic]; //赋值 strikeLabel.attributedText = attribtStr; [self.view addSubview:strikeLabel];
添加下划线
UILabel *underlineLabel =[[UILabel alloc]initWithFrame:(CGRectMake(10,10,50,30))]; NSString *textStr =[NSStringWithFormat:@"%@元"，primeCost]; //下划线 NSDictionary *attirbtDic =@{NSUnderlineStyleAttributedString alloc]initWithString:textStr attributes:attribtDic]; //赋值 underlineLabel.attributedText = attribtStr; [self.view addSubview:underlineLabel];
效果如图所示：
