• 今天接触了属性字符串的部分用法，发现真是好用啊！以下是部分用法：

NSMutableAttributedString* attributedStr = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"合计: ¥%.2f",model.goodsCount * model.goodsModel.price]];

NSRange range1 = NSMakeRange(0, 3);

NSRange range2 = NSMakeRange(3, attributedStr.length - 3);

[attributedStr addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHexString:@"#6c6c6c"] range:range1];//设置前面三个字符的颜色

[attributedStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:14.f] range:range1];//设置前面三个字符的字号大小

[attributedStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:18.f] range:range2];//设置后面字符的颜色

[attributedStr addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHexString:@"#fc4001"] range:range2];//设置后面字符的字号大小

UILable* label=[ [UILabel alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight - 64 - 64)]];

label.attributedText = attributedStr;

其实际效果如下：
