如何将 CSS 应用于 iOS NSAttributedString

Question

我在一个 iOS 项目中工作，我有这个 HTML 文本需要在 UITextView 中显示：

<a href="http://google.com" target="_blank" rel="nofollow" title="Link: http://google.com">http://google.com/</a><br><span class="wysiwyg-color-d24b57 ">TEST<br><i><span class="wysiwyg-color-704938 ">TEST2<br></span></i></span><div class="wysiwyg-text-align-left "><span class="wysiwyg-color-d24b57 "><span class="wysiwyg-color-704938 "><u><span class="wysiwyg-color-3a529c ">Test3<br>TEST4<br><br></span></u><span class="wysiwyg-color-3a529c wysiwyg-font-size-x-large ">Test5</span><u><span class="wysiwyg-color-3a529c "><br><br><br></span></u></span></span></div>

到目前为止，我已经创建了 NSAttributedString 和 UITextView：

NSAttributedString *attributedString = [[NSAttributedString alloc]
                                            initWithData: [example.text dataUsingEncoding:NSUnicodeStringEncoding]
                                            options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType }
                                            documentAttributes: nil
                                            error: nil
                                            ];


UITextView *textView = [[UITextView alloc] init];
textView.frame = [node labelFrame];
textView.attributedText = attributedString;
textView.editable = NO;
textView.selectable = YES;
textView.backgroundColor = [UIColor clearColor];

return textView;

现在我必须对其应用所见即所得的 CSS，因为目前，颜色、字体大小和对齐方式都不起作用。

有人知道怎么做吗？

提前致谢！

你可以喜欢这种方式

let divHtml = "<div style=\"font-family:Helvetica;font-size:14px;line-height:22px\" >" + YOUR TEXT + "</div>"
        let attributedString = try! NSAttributedString(data: divHtml.dataUsingEncoding(NSUTF8StringEncoding)!, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)

textView.attributedText = attributedString
