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

I believe this is what you are looking for:

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

Return Value:

A new string made by replacing in the receiver all percent escapes with the matching characters as determined by the given encoding. It returns nil if the transformation is not possible, for example, the percent escapes give a byte sequence not legal in encoding.
