Basic FTP methods in Cocoa

Two methods are required: A method that takes a path and ftp URL and asynchronously uploads it with an incremental progress (bytes transferred) event, and completed/failed events. A method that synchronously sends an FTP command (e.g. to create/list directories) returning the result. It would be great if this did SFTP too, but not essential. Additional parameters to specify active/passive mode should be included. These methods would be integrated into an existing Cocoa framework, and would need to utilise the same events that are already present in it. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
