You have to know the exact structure of your html string and you would need to modify the html string to change the font and font size. Add/Modify html tags around required text in order to change font and/or font size.

Use NSMutableString instead of NSString and then modify your string according to your requirement.

Yes, you can do it by using html tags.

NSString *stringToLoad = [NSString stringWithFormat:@"<html><center><font size=+5>%@</font></center></html>", myString];

You need to convert your string to valid html string and then set font-family for html string:

NSString *myDescriptionHTML = [NSString stringWithFormat:@"<html> \n"
                                "<head> \n"
                                "<style type=\"text/css\"> \n"
                                "body {font-family: \"%@\"; font-size: %@;}\n"
                                "</style> \n"
                                "</head> \n"
                                "<body>%@</body> \n"
                                "</html>", @"HelveticaNeue", [NSNumber numberWithInt:kFieldFontSize], myString];
