将自定义字体添加到iOS中的UITextView中已解析的HTML内容时，斜体字体不起作用

Question

I have a textview where I'm parsing and HTML content and it works fine. But the tags marked italic doesn't work. I'm using a custom font. Below is the sample code:

NSString *messages = @"<b>Bold</b><br><i>Italic</i><p> <del>Deleted</del><p>List<ul><li>Coffee</li><li type='square'>Tea</li></ul><br><a href='URL'>Link </a>";

NSString *stringWithFont = [NSString stringWithFormat:@"<span style=\"font-family: OpenSans; font-size: 14\">%@</span>", messages];

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

_notificationTextView.attributedText = attributedString;

This is how it looks, note that the italic didn't work.

UPDATE

Currently my project includes all Opensans font set like, regular, italic, bold, semibold etc. So, if I remove the light font or its reference from my project it seems to work. Looks like some kind of weird conflict with regular and light font. Anybody has any ideas?

It works for me. Showing italic text. Use

     self.txtView.attributedText=attributedString;
