1、获取设备信息

}

给文字添加删除线
在原有的属性字典里添加 NSBaselineOffsetAttributeName (基线偏移值:取值为NSNumber （float），正值上偏，负值下偏)就可以了 。
iOS10.3之前的写法是：
NSAttributedString *attributedString = [[NSAttributedString alloc]
initWithString:goodsprice attributes:@{
NSStrikethroughStyleAttributeName :@(NSUnderlineStyleSingle),
NSStrikethroughColorAttributeName : UIColorFromHexValue(0xBBBBBB)
}];
seckillLabel.attributedText = attributedString;
iOS10.3之后的写法是：
NSAttributedString *attributedString = [[NSAttributedString alloc]
initWithString:goodsprice attributes:@{
NSStrikethroughStyleAttributeName : @(NSUnderlineStyleSingle),
NSStrikethroughColorAttributeName : UIColorFromHexValue(0xBBBBBB),
NSBaselineOffsetAttributeName:@(0)}];//NSBaselineOffsetAttributeName 设置基线偏移值。取值为NSNumber （float），正值上偏，负值下偏
cell.seckillLabel.attributedText = attributedString;
效果图
