NSMutableAttributedString 是一个很强悍的富文本处理字符串，可以方便的实现一个字符串中某个字符的样式处理。我把我下面代码实现的功能步骤说一下:首先拼接两个字符串，然后给前前半部分和后半部分字符串分别实现不同样式，最后在给后半部分的字符串增加删除线.... 如果不用到NSMutableAttributedString 实现起来不但麻烦不说，而且不能保证百分之百的准确: 下面先截图 然后上代码
(←就是它了)
NSDictionary *singleDictionary=[[NSDictionary alloc]initWithObjectsAndKeys:@"pic1",@"imagePath",@"雅致汉斯套餐",@"title",@"重庆only you婚礼策划",@"content",@"6666",@"currentPrice",@"8888",@"truePrice", nil]; //价格 UILabel *PriceLabel=[[UILabel alloc]initWithFrame:CGRectMake(DEVICE_Width*0.5+6,89-22,DEVICE_Width*0.5-6, 15)]; PriceLabel.textColor=COLOR(249, 135, 164); PriceLabel.font=[UIFont systemFontOfSize:15]; PriceLabel.text= [NSString stringWithFormat:@"%@%@%@%@",@"￥",[singleDictionary objectForKey:@"currentPrice"],@" ￥",[singleDictionary objectForKey:@"truePrice"]]; NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString: PriceLabel.text]; [str addAttribute:NSForegroundColorAttributeName value:COLOR(249, 135, 164) range:NSMakeRange(0,str.length)]; //设置字体颜色 [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:15] range:NSMakeRange(0, str.length)]; //设置字体大小 [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:11]range:NSMakeRange(0, 1)]; NSString *getCutStr= [singleDictionary objectForKey:@"currentPrice"]; [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:11] range:NSMakeRange(getCutStr.length+2, str.length-(getCutStr.length+2))]; //设置字体大小 [str addAttribute:NSForegroundColorAttributeName value:COLOR(149,150,151) range:NSMakeRange(getCutStr.length+2, str.length-(getCutStr.length+2))]; //设置字体颜色 //删除线 int beginThroughIndex= [NSString stringWithFormat:@"%@", [singleDictionary objectForKey:@"currentPrice"]].length+3; [str addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlinePatternSolid|NSUnderlineStyleSingle) range:NSMakeRange(beginThroughIndex, str.length-beginThroughIndex)]; [str addAttribute:NSStrikethroughColorAttributeName value:COLOR(149,150,151) range:NSMakeRange(beginThroughIndex, str.length-beginThroughIndex)];
PriceLabel.attributedText = str; PriceLabel.textAlignment=NSTextAlignmentLeft; PriceLabel.numberOfLines = 0; [cell addSubview:PriceLabel];
