价格不同字体大小的富文本实现方式

1 富文本 的实现效果

 

 

2 方法的封装

 

- (void)makeValueStringChangeWithPrice:(NSString *)price unit:(NSString *)unit

{

    NSString *str = [NSStringstringWithFormat:@"￥ %@元/%@",price,unit];

    _valueLabel.text = str;

   

    NSMutableString * subtitlelabelStr = [NSMutableStringstringWithFormat:@"￥ %@元/%@",price,unit];

    _valueLabel.text = subtitlelabelStr;

   

    NSMutableAttributedString *attributedString = [[NSMutableAttributedStringalloc] initWithString:_valueLabel.text];

   

    [attributedString setAttributes:@{NSForegroundColorAttributeName:NF_Color_C19,NSFontAttributeName:[UIFontsystemFontOfSize:Near_Final_Font_T2]

                                      }range:NSMakeRange(0, 2)];

    NSRange tmpRange = [[[attributedString string] lowercaseString] rangeOfString:@"元"];

    NSRange valueRange;

    valueRange.location = 2;

    valueRange.length = tmpRange.location-1;

    [attributedString addAttributes:@{NSForegroundColorAttributeName:NF_Color_C19,NSFontAttributeName:[UIFontsystemFontOfSize:Near_Final_Font_T5]}range:valueRange];

   

    NSRange unitRange;

    unitRange.location = tmpRange.location+1;

    unitRange.length = [_valueLabel.textlength]-unitRange.location;

    [attributedString setAttributes:@{NSForegroundColorAttributeName:NF_Color_C19,NSFontAttributeName:[UIFontsystemFontOfSize:Near_Final_Font_T2]}range:unitRange];

   

    NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStylealloc] init];

    paragraph.alignment = NSTextAlignmentRight;

    [attributedString addAttribute:NSParagraphStyleAttributeNamevalue:paragraph range:NSMakeRange(0, [_valueLabel.textlength])];

   

    _valueLabel.attributedText = attributedString;

    _valueLabel.frame = CGRectMake(self.bounds.size.width-200-10, CGRectGetMinY(self.scoreLabel.frame)-10-_valueLabel.contentSize.height, 200, 16);
