    There isn’t an NSString method that does that. You’ll have to write your own function that does string replacements. It is sufficient to do the following replacements:

    • ‘&’ => “&”
    • ‘”‘ => “"”
    • ‘\” => “'”
    • ‘>’ => “>”
    • ‘<‘ => “&lt;”

    Something like this should do (haven’t tried):

    [[[[[myStr stringByReplacingOccurrencesOfString: @"&" withString: @"&amp;"]
 stringByReplacingOccurrencesOfString: @"\"" withString: @"&quot;"]
 stringByReplacingOccurrencesOfString: @"'" withString: @"&#39;"]
 stringByReplacingOccurrencesOfString: @">" withString: @"&gt;"]
 stringByReplacingOccurrencesOfString: @"<" withString: @"&lt;"];
