給文字添加刪除線
在原有的屬性字典里添加 NSBaselineOffsetAttributeName (基線偏移值:取值為NSNumber （float）固额，正值上偏十偶，負(fù)值下偏)就可以了 涵叮。
iOS10.3之前的寫(xiě)法是：
NSAttributedString *attributedString = [[NSAttributedString alloc]
initWithString:goodsprice attributes:@{
NSStrikethroughStyleAttributeName :@(NSUnderlineStyleSingle),
NSStrikethroughColorAttributeName : UIColorFromHexValue(0xBBBBBB)
}];
seckillLabel.attributedText = attributedString;
iOS10.3之后的寫(xiě)法是：
NSAttributedString *attributedString = [[NSAttributedString alloc]
initWithString:goodsprice attributes:@{
NSStrikethroughStyleAttributeName : @(NSUnderlineStyleSingle),
NSStrikethroughColorAttributeName : UIColorFromHexValue(0xBBBBBB),
NSBaselineOffsetAttributeName:@(0)}];//NSBaselineOffsetAttributeName 設(shè)置基線偏移值萌踱。取值為NSNumber （float）厌漂，正值上偏哨啃，負(fù)值下偏
cell.seckillLabel.attributedText = attributedString;
效果圖
