从NSAttributedString生成HTML文件

Question

最近，我的项目遇到了问题。我需要将NSAttributedString转换为HTML文件。解决方案点击here对我不起作用，因为想要仅使用TagName和idName以及ClassName输出HTML文件，同时输出CSS样式文件以控制HTML文件的显示方式。 这是我的示例代码，我希望你能得到我的意图：

    - (NSDictionary *)html
    {
        NSTextStorage *textStorage = [self contents];
        NSArray *arr = [textStorage paragraphs];
        // Initialize the CSS dictionay
        NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                     nil];

        NSEnumerator *paragraphEnumerator;
        paragraphEnumerator = [arr objectEnumerator];
        NSAttributedString *paragraph;
        NSMutableArray *paragrapHTMLStrings = [[NSMutableArray alloc] initWithCapacity:[arr count]];

        NSMutableString *cssString = [[NSMutableString alloc] initWithCapacity:0];
        [cssString appendString:@"div{"];
        [cssString appendString:[NSString stringWithFormat:@"-webkit-column-count:%ld;", self.columnCount]];
        [cssString appendString:[NSString stringWithFormat:@"width:%fpx;", self.bounds.size.width]];
        [cssString appendString:[NSString stringWithFormat:@"height:%fpx;", self.bounds.size.height]];
        [cssString appendString:@"}"];


        [dict setObject:cssString forKey:@"css"];

        while (paragraph = [paragraphEnumerator nextObject]) {
            // initialize
            NSUInteger length;
            NSRange effectiveRange = NSMakeRange(0, 0);
            id attributeValue;

            length = [paragraph length];
            // get the font attributes
            attributeValue = [paragraph attribute:NSFontAttributeName atIndex:NSMaxRange(effectiveRange) effectiveRange:&effectiveRange];
            NSLog(@"font is %@", [attributeValue fontName]);
            NSLog(@"font-size is %f", [[[attributeValue fontDescriptor] objectForKey:NSFontSizeAttribute] floatValue]);
            NSMutableString *htmlString = [NSMutableString stringWithFormat:@"", [attributeValue fontName],
                                           [[[attributeValue fontDescriptor] objectForKey:NSFontSizeAttribute] floatValue]];

            [htmlString appendString:[paragraph string]];
            [htmlString appendString:@"
"];
            NSLog(@"htmlString is %@", htmlString);
            [paragrapHTMLStrings addObject:htmlString];
            htmlString = nil;


        }

        NSMutableString *htmlStringOfGraphToReturn = [NSMutableString stringWithString:@""];
        NSString *stringToAdd;
        NSEnumerator *stringEnumerator;
        stringEnumerator = [paragrapHTMLStrings objectEnumerator];

        while (stringToAdd = [stringEnumerator nextObject])
        {
            [htmlStringOfGraphToReturn appendString:stringToAdd];
        }
        [htmlStringOfGraphToReturn appendString:@""];

        [dict setObject:htmlStringOfGraphToReturn forKey:@"html"];

        // test part
        CSSSetGenerator *generater = [[CSSSetGenerator alloc] init];

        NSMutableString *string = [generater outputCSSStyleContent:self];
        NSLog(@"%@", string);
        return dict;
    }

我从Github得到了解决方案，有一个名为DTCoreText的开放项目。我希望这可能对某些人有用。
