iOS Label添加删除线

@import url(/css/cuteeditor.css);

在做优惠价格的时候需要用到删除线，但是网上的删除线都是创建一个类继承自UILabel,然后重写drawRect方法重绘Label，其实苹果的NSAttributedString就可以实现这一点。

代码如下：

NSString *lastPrice = @"¥12.25";

NSUInteger length = [lastPrice length];

NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] initWithString:lastPrice];

[attri addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlinePatternSolid | NSUnderlineStyleSingle) range:NSMakeRange(0, length)];

[attri addAttribute:NSStrikethroughColorAttributeName value:(id)[UIColor blackColor] range:NSMakeRange(0, length)];

[lastPriceLabel setAttributedText:attri];
