Objective-C

Upload Text Content to an FTP File

Demonstrates the Chilkat Ftp2.PutFileFromTextData method, which uploads text (encoded with a charset) directly to a remote file. The arguments are the remote filename, the text, and the charset.

Background: This is the most direct way to create a small remote text file from a string in your program — no StringBuilder and no local file needed. It is ideal for writing a short status file, a marker, or generated configuration. The charset controls the encoding of the file content.
