(Objective-C) IMAP Download All Email One at a TimeDemonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) Note: This example requires Chilkat v11.0.0 or greater.
#import <CkoImap.h> #import <NSString.h> #import <CkoEmail.h> BOOL success = NO; CkoImap *imap = [[CkoImap alloc] init]; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Connect to an IMAP server. // Use TLS imap.Ssl = YES; imap.Port = [NSNumber numberWithInt:993]; success = [imap Connect: @"imap.example.com"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Login success = [imap Login: @"myLogin" password: @"myPassword"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Select an IMAP mailbox success = [imap SelectMailbox: @"Inbox"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Once the mailbox is selected, the NumMessages property // will contain the number of messages in the mailbox. // You may loop from 1 to NumMessages to // fetch each message by sequence number. BOOL bUid = NO; NSString *mimeStr = 0; int i; int n = [imap.NumMessages intValue]; for (i = 1; i <= n; i++) { // Download the email by sequence number. mimeStr = [imap FetchSingleAsMime: i bUid: bUid]; // ... your application may process each MIME string... } // An alternative is to download each email in the form of an // email object, like this: CkoEmail *email = [[CkoEmail alloc] init]; for (i = 1; i <= n; i++) { // Download the email by sequence number. success = [imap FetchEmail: NO msgId: i bUid: bUid email: email]; // ... your application may process the email object... } // Disconnect from the IMAP server. success = [imap Disconnect]; |
