iOS 简单使用富文本格式对一个字符串进行不同设置

            NSMutableAttributedString *myText =  [[NSMutableAttributedStringalloc] initWithString:[NSStringstringWithFormat:@"%@ %@",titleText,priceText]];

            [myText beginEditing];

            [myText addAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:16]range:NSMakeRange(0, titleText.length)];

            [myText addAttribute:NSForegroundColorAttributeNamevalue:[UIColordarkGrayColor] range:NSMakeRange(0, titleText.length)];

            [myText addAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:30]range:NSMakeRange(titleText.length, myText.length-titleText.length)];

            [myText addAttribute:NSForegroundColorAttributeNamevalue:[UIColorredColor] range:NSMakeRange(titleText.length, myText.length-titleText.length)];

            [myText endEditing];

            moneyLabel.attributedText = myText;
