Question

I created an iPhone app which users search news, the app runs the search through a PHP script i wrote and uses Objective C string replace to take out all of the ‘,-_” symbols and replace them with + however i saw last night that a search had come through like this: “Beyonc%C3%A8” i was just wondering what this meant, its clearly trying to be Beyonce, but has someone used an accent over the ‘e’ and screwed the URL up?

Answer 1

There’s more to URL encoding than “+” signs. Most of it is percent escaping.

In addition to replacing “+” with ” “, you should also do this.

NSString *decodedString = [encodedString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
