How to duplicate JavaScript unescape() Function in Objective-C

I have a string that's encoded with JavaScript escape() that i need to decode in objective-c, I've searched everywhere for a solution but I can't even find what type of encoding this is.

Sample string: 

%3Cdiv%20id%3D%27wrapper%27%3E%3Cp%3EHello%20World%21%3C/p%3E%3C/div%3E

There is an NSString function you can use: stringByReplacingPercentEscapesUsingEncoding:

From the documentation:

Returns a new string made by replacing in the receiver all percent escapes with the matching characters as determined by a given encoding.

Typically you should be using NSUTF8StringEncoding for the encoding.

Example usage:

NSString *escaped = @"%3Cdiv%20id%3D%27wrapper%27%3E%3Cp%3EHello%20World%21%3C/p%3E%3C/div%3E";
NSString *unescaped = [escaped stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
