I am trying to encode a URL request parameter in order to avoid using reserved characters. The main reason for this is that I have to send a POST request to an API that receives a data from an encrypted URL parameter, so I want to avoid sending a request where this parameter has reserved characters. I been searching for some method an I found this.

[parameterData stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet URLHostAllowedCharacterSet]]

But it does not encode all characters.
