html - 如何根据html标签在UILabel中显示html文本？

Question

   NSAttributedString *attrString = [[NSAttributedString alloc] initWithData:[stringFromHtml dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} documentAttributes:nil error:nil]
   self.textLabel.attributedText = attrString;
   self.textLabel.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:14.0];

此代码忽略 <b> </b>和 <i> </i>标签，但对另一个标签使用react (\t\r\n
)

已编辑:

此代码仅适用于我，然后我评论第二行 ( NSFontAttributeName ) - 在这种情况下，字体是默认的，标签如 <b>, <i>不会被忽略。 但是如果我想要我的字体样式 - 标签再次被忽略...... wtf？ :)

    NSMutableAttributedString *attrHTMLText = [[[NSAttributedString alloc] initWithData:[eventText dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)} documentAttributes:nil error:nil] mutableCopy];
    [attrHTMLText addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"HelveticaNeue-Light" size:14.0] range:NSMakeRange(0, attrHTMLText.length)];
    [attrHTMLText addAttribute:NSForegroundColorAttributeName value:[UIColor darkGrayColor] range:NSMakeRange(0, attrHTMLText.length)];
    self.textLabel.attributedText = attrHTMLText;

将 NSAttributedString 与 NSHTMLTextDocumentType 之类的选项一起用作 NSDocumentTypeDocumentAttribute

//create NSMutableAttributedString for adding attributes as per required
NSMutableAttributedString *attrHTMLText = [[[NSAttributedString alloc] initWithData:[yourHTMTextHere dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)} documentAttributes:nil error:nil] mutableCopy];
//set font here
[attrHTMLText addAttribute:NSFontAttributeName value:yourLabel.font range:NSMakeRange(0, attrHTMLText.length)];
//set color here
[attrHTMLText addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, attrHTMLText.length)];

//Now set attribute text to your Label
yourLabel.attributedText = attrHTMLText;
