如何在iPhone中实现URL编码？

Question

I am developing an application in which I need to encode URL. I tried using http://simonwoodside.com/weblog/2009/4/22/how_to_really_url_encode/ and [NSString stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]] but its not working out for me. Is there any alternate URL encoder class for iphone like java? How to achieve it?? Thanks in advance...
