    You can try NSAttributedString+DDHTML. AFAIK it doesn't depend on WebKit and I used it successfully for simple HTMLs. I haven't tried using it in the background thread, but I suppose it shouldn't be a problem.

    And watch out - it may crash when HTML includes font which is unavailable on iOS. I've issued a pull request for that.

    Yes you can't it in a background thread only on main thread. Use Oliver Drobnik's NSAttributedString+HTML class.

    Code would be something like this -

    NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithHTML:<html> dataUsingEncoding:NSUTF8StringEncoding] documentAttributes:nil];
