Append a Local File to a Remote FTP File

See more FTP Examples

Demonstrates the Chilkat Ftp2.AppendFile method, which appends the contents of a local file to a remote file. The first argument is the local file path and the second is the remote file path. It uses the FTP APPE command.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

#import <CkoFtp2.h>

BOOL success = NO;

//  Demonstrates the Ftp2.AppendFile method, which appends the contents of a local file to a remote
//  file.  The 1st argument is the local file path and the 2nd is the remote file path.

CkoFtp2 *ftp = [[CkoFtp2 alloc] init];

ftp.Hostname = @"ftp.example.com";
ftp.Username = @"myFtpLogin";

//  Normally you would not hard-code the password in source.  You should instead obtain it
//  from an interactive prompt, environment variable, or a secrets vault.
ftp.Password = @"myPassword";

success = [ftp Connect];
if (success == NO) {
    NSLog(@"%@",ftp.LastErrorText);
    return;
}

//  Uses the FTP APPE command.  On a server with normal APPE behavior, a missing remote file is
//  created; otherwise the local bytes are appended to the end of the existing remote file.
