Automatically Determine FTP Proxy Method

See more FTP Examples

Tries each of the five possible ProxyMethod settings and returns the value (1-5) of the ProxyMethod that succeeded. Objective-C

#import <CkoFtp2.h>

BOOL success = NO;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

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

ftp.Hostname = @"www.example-code.com";
ftp.Username = @"example-code.com";
ftp.Password = @"****";

ftp.ProxyHostname = @"ftp.myproxyhost.com";
ftp.ProxyPort = [NSNumber numberWithInt:21];
//  Note: Your FTP Proxy server may or may not require authentication.
ftp.ProxyUsername = @"myProxyUsername";
ftp.ProxyPassword = @"myProxyPassword";

//  The ProxyMethod should be an integer value between 1 and 5.
//  If you know your FTP proxy server's authentication scheme,
//  you may set it directly.  To determine the ProxyMethod,
//  call DetermineProxyMethod.  A return value of -1 indicates a failure.
//  A return value of 0 indicates that nothing worked.
//  A return value of 1-5 indicates the ProxyMethod that was 
//  successful, and this should be the value used for the ProxyMethod
//  property.

int pMethod = [[ftp DetermineProxyMethod] intValue];
NSLog(@"%d",pMethod);
