Objective C HTML escape/unescape

Question

Wondering if there is an easy way to do a simple HTML escape/unescape in Objective C. What I want is something like this psuedo code:

NSString *string = @\"         


        

Answer 1

This is an easy to use NSString category implementation:

• http://code.google.com/p/qrcode-scanner-live/source/browse/trunk/iphone/Classes/NSString%2BHTML.h
• http://code.google.com/p/qrcode-scanner-live/source/browse/trunk/iphone/Classes/NSString%2BHTML.m

It is far from complete but you can add some missing entities from here: http://code.google.com/p/statz/source/browse/trunk/NSString%2BHTML.m

Usage:

#import "NSString+HTML.h"

NSString *raw = [NSString stringWithFormat:@"
"];
NSString *escaped = [raw htmlEscapedString];
