(Objective-C) SFTP Simplified Upload

Demonstrates how to upload a file to an SSH server in the simplest way -- by calling UploadFileByName and passing remote and local filepaths.

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

CkoSFtp *sftp = [[CkoSFtp alloc] init];

// Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = [NSNumber numberWithInt:15000];
sftp.IdleTimeoutMs = [NSNumber numberWithInt:15000];

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.

int port = 22;
BOOL success = [sftp Connect: hostname port: [NSNumber numberWithInt: port]];

    NSLog(@"%@",sftp.LastErrorText);
    return;

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.

// After authenticating, the SFTP subsystem must be initialized:
success = [sftp InitializeSftp];
if (success != YES) {
    NSLog(@"%@",sftp.LastErrorText);
    return;

// Upload from the local file to the SSH server.
// Important -- the remote filepath is the 1st argument,
// the local filepath is the 2nd argument;
NSString *remoteFilePath = @"hamlet.xml";
NSString *localFilePath = @"c:/temp/hamlet.xml";
