iOS10.3 UILable中划线失效问题

iOS10.3系统的一个Bug，在UILable中含有中文时，中划线会失效

    NSString *priceStr = [NSString stringWithFormat:@"%.2f元",payInfo.originalPrice];

1、原来添加中划线方式（在iOS10.3系统后失效）

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

//    NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc] initWithString:priceStr attributes:attribtDic];

2、解决办法

    NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc] initWithString:priceStr];

    [attribtStr setAttributes:@{NSStrikethroughStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle], 　　NSBaselineOffsetAttributeName : @(NSUnderlineStyleSingle)} range:NSMakeRange(0, priceStr.length)];

　　self.originLable.attributedText = attribtStr;
