(Objective-C) Async Upload (Append) Email to an IMAP MailboxUse the AppendMailAsync method call to append an email to an IMAP mailbox.
#import <CkoImap.h> #import <CkoEmail.h> #import <CkoTask.h> // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkoImap *imap = [[CkoImap alloc] init]; // Connect to an IMAP server. // Use TLS imap.Ssl = YES; imap.Port = [NSNumber numberWithInt:993]; BOOL success = [imap Connect: @"MY-IMAP-DOMAIN"]; if (success != YES) { NSLog(@"%@",imap.LastErrorText); return; } // Login success = [imap Login: @"MY-IMAP-LOGIN" password: @"MY-IMAP-PASSWORD"]; if (success != YES) { NSLog(@"%@",imap.LastErrorText); return; } // Create a simple email with 2 recipients. CkoEmail *email = [[CkoEmail alloc] init]; email.From = @"support@chilkatsoft.com"; [email AddTo: @"Chilkat Sales" emailAddress: @"sales@chilkatsoft.com"]; [email AddTo: @"Chilkat GMail" emailAddress: @"chilkat.support@gmail.com"]; email.Body = @"This is a test email."; email.Subject = @"This is a test email."; // Imagine we've sent this email via SMTP, and now we want to // save the email to our "Sent" mailbox. On GMail, the mailbox name // for sent email is "[Gmail]/Sent Mail". // Call the async version of the AppendMail method to return a task object. CkoTask *task = [imap AppendMailAsync: @"[Gmail]/Sent Mail" email: email]; if (imap.LastMethodSuccess != YES) { NSLog(@"%@",imap.LastErrorText); return; } // Schedule the task for running on the thread pool. This changes the task's state // from Inert to Live. The task is now running... success = [task Run]; if (success != YES) { NSLog(@"%@",task.LastErrorText); return; } // ------------------------------------------------------------------------------- // The following is a general note that applies to all programming languages: // ------------------------------------------------------------------------------- // Your application can keep a reference to the task object and periodically check back later to see if it's finished. // If your programming language is one that supports callbacks, then the TaskCompleted callback can // be setup to be called when the task completes. (See the "Async" category on example-code.com for more information.) // // NOTE: This is very important: A TaskCompleted callback runs in the background thread. // (All callbacks from an async task, such as AbortCheck, PercentDone, ProgressInfo, etc. are in the background thread.) // An application that uses TaskCompleted must be very careful. // For example, user interface elements (such as labels, text boxes, etc.) may not be directly // accessible from a background thread, and could crash the application if directly accessed. Also, attempting to debug // code running in a background thread from an IDE, especially an older IDE (such as VB6) is likely to crash the IDE. |
