You can apparently route through NSAttributedString (found via StackOverflow):
NSAttributedString *s = [[NSAttributedString alloc]
initWithString:sourceString];
NSDictionary *documentAttributes = @{NSDocumentTypeDocumentAttribute:
NSHTMLTextDocumentType};
NSData *htmlData = [s dataFromRange:NSMakeRange(0, s.length)
documentAttributes:documentAttributes error:NULL];
NSString *htmlString = [[NSString alloc] initWithData:htmlData
encoding:NSUTF8StringEncoding];
