Renaming folder and Moving folder in FTP via iOS

Renaming folder and Moving folder in FTP via iOS

I am trying to rename a folder in FTP via ios. I have implemented Black
Raccoon library for FTP. Like all other libraries I've com across, it has
options for creating, deleting and uploading files to a specific ftp.
However renaming a folder or moving a folder are absent. I've read the
CFNetworking doc provided in Apple developer site. here also they have
completely avoided the question of renaming a folder or moving a folder.
The question is how can I approach this problem? Should I try to use FTP
commands? If so, how should I use these commands in objective C?
