从NSAttribute字符串生成HTML文件

最近，我在我的项目中遇到了一个问题。我需要将NSAttribute字符串转换为HTML文件。解决方案单击对我不起作用，因为我只想输出带有标记名、idName和ClassName的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，我希望您能得到我的建议：

- (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; } -（NSDictionary*）html { NSTextStorage*textStorage=[self contents]； NSArray*arr=[文本存储段落]； //初始化CSS词汇表 NSMutableDictionary*dict=[NSMutableDictionary Dictionary WithObjectsAndKeys: 零]； N分子*段落枚举器； 段落枚举器=[arr objectEnumerator]； NSAttribute字符串*段落； NSMUTABLEARRY*段落tmlstrings=[[NSMUTABLEARRY alloc]initWithCapacity:[arr count]]； NSMutableString*cssString=[[NSMutableString alloc]initWithCapacity:0]； [cssString appendString:@“div{”]； [CSSSString appendString:[NSString stringWithFormat:@”-webkit列计数：%ld；“，self.columnCount]]； [CSSSString appendString:[NSString stringWithFormat:@“宽度：%fpx；”，self.bounds.size.width]； [CSSSString appendString:[NSString stringWithFormat:@“高度：%fpx；”，self.bounds.size.height]； [cssString appendString:@“}”]； [dict setObject:cssString forKey:@“css”]； 而（段落=[段落枚举器下一个对象]）{ //初始化 整数长度； NSRange effectiveRange=NSMakeRange（0,0）； id属性值； 长度=[段落长度]； //获取字体属性 attributeValue=[段落属性：NSFontAttributeName atIndex:NSMaxRange（effectiveRange）effectiveRange:&effectiveRange]； NSLog（@“字体为%@，[attributeValue fontName]）； NSLog（@“字体大小为%f”，[[[attributeValue fontDescriptor]objectForKey:NSFontSizeAttribute]floatValue]）； NSMutableString*htmlString=[NSMutableString stringWithFormat:@]，[attributeValue fontName]， [[[attributeValue fontDescriptor]objectForKey:NSFontSizeAttribute]floatValue]]； [htmlString appendString:[段落字符串]]； [htmlString appendString:@“

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