iOS开发给Label加下划线、中划线

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 = [NSString stringWithFormat:@"%@元", primeCost];
 
// 下划线

NSDictionary *attribtDic = @{NSUnderlineStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};

NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc]initWithString:textStr attributes:attribtDic];
 
//赋值
underlineLabel.attributedText = attribtStr;
 
[self.view addSubview:underlineLabel];
