因为有中文所以 中线无效
NSDictionary *attribtDic = @{NSStrikethroughStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle],NSStrikethroughColorAttributeName:[UIColor orangeColor]};
NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc]initWithString:@"原¥1000" attributes:attribtDic];
self.myLabel.attributedText = attribtStr;
去掉字符串中的‘原’，就能显示了
很奇怪，为什么没有中文就能显示，但‘¥’是在中文环境下打出来的，为什么要显示
如果有中文文子怎么呢？
//看有哪里不一样
NSDictionary *attribtDic = @{NSStrikethroughStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle],NSBaselineOffsetAttributeName : @(NSUnderlineStyleSingle),NSStrikethroughColorAttributeName:[UIColor orangeColor]};
NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc]initWithString:@"原来如此¥1000" attributes:attribtDic];
self.myLabel.attributedText = attribtStr;
成功！
