HTML character decoding in Objective-C / Cocoa Touch

Question

First of all, I found this: Objective C HTML escape/unescape, but it doesn\'t work for me.

My encoded characters (come from a RSS feed, btw) look like this: &a

Nobody seems to mention one of the simplest options: Google Toolbox for Mac
(Despite the name, this works on iOS too.)

https://github.com/google/google-toolbox-for-mac/blob/master/Foundation/GTMNSString%2BHTML.h

/// Get a string where internal characters that are escaped for HTML are unescaped 
//
///  For example, '&' becomes '&'
///  Handles   and 2 cases as well
///
//  Returns:
//    Autoreleased NSString
//
- (NSString *)gtm_stringByUnescapingFromHTML;

And I had to include only three files in the project: header, implementation and GTMDefines.h.
