urldecode in objective-c

Question

I\'m dealing with an urlencoded string in objective-c. Is there a foundation function that actually reverse the urlENCODING?

The string received is like: K%FChlschr

Answer 1

Apple has depreacted stringByReplacingPercentEscapesUsingEncoding: since iOS9. Please use stringByRemovingPercentEncoding.

The new method, Returns a new string made from the receiver by replacing all percent-encoded sequences with the matching UTF-8 characters.

Example:

NSString *encodedLink = @"hello%20world";
NSString *decodedUrl = [encodedLink stringByRemovingPercentEncoding];
NSLog (@"%@", decodedUrl);

Output:

hello world
