How to upload FILE via FTP ?

Is there a Cocoa API to upload file to a web site ?
here) with your favorite command line tool (ftp, sftp, curl, etc.)
3. You can't use standard NSFileManager methods once you have mounted the remote FTP file system using mount_ftp (man mount_ftp), because currently the mount is made read-only, but the method works for download. You can use mount_ftp from a pipe or NSTask:
mkdir /tmp/my_remote_ftp_node
mount_ftp my_login:my_password@ftp.my_domain /my_remote_ftp_node
# put your copy instruction here, example
# cp -r my_source /tmp/my_remote_ftp_node/my_destination
umount -f /tmp/my_remote_ftp_node
Or in C
mount("ftp", "/tmp/my_remote_ftp_node", 0, (void *)"my_login:my_password@ftp.my_domain");
4. Greg Hulands's has written a basic FTPConnection class
5. The "URL Acess Scripting" AppleScript extension allows upload and download of files, see WebMasterMac and tidBits
6. You could pipe to curl or launch a NSTask...
7. there is also the wput utility, symetric to GNU wget
8. The NSData method writeToURL:atomically: can be used with a ftp://user:password@host/path_to_file url.
9. Last but not least, CoreFoundation includes CFFTP
The following methods are available from a Cocoa application to handle ftp communication:
1. You can link to libcurl (man libcurl) or other ftp client libraries
2. You can use expect (see our example

Though all of the techniques posted above do work to some extent, I have found a much easier and more reliable way to add FTP to Cocoa programs. This is to create a NSTask wrapping the Unix command FTP. It will allow you to execute any FTP commands, such as uploading and downloading files.
I have provided a sample application named Workbench on my site, which demonstrates the use of NSTasks. It is a fully featured app which allows teachers to post homework on a server so students can see it. If you have any questions about NSTasks or FTP, feel free to email me at ericbrunstad@excite.com. I know how intimidating NSTasks can be!
