(Objective-C) Get IMAP UID from Email HeaderDemonstrates how to get the IMAP UID from an email header. After fetching an email or header using IMAP, the UID is contained in the ckx-imap-uid header field. Note: This example requires Chilkat v11.0.0 or greater.
#import <CkoImap.h> #import <CkoMessageSet.h> #import <CkoEmailBundle.h> #import <CkoEmail.h> #import <NSString.h> BOOL success = NO; // This example requires 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]; success = [imap Connect: @"imap.someMailServer.com"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Login success = [imap Login: @"login" password: @"password"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Select an IMAP mailbox success = [imap SelectMailbox: @"Inbox"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } BOOL fetchUids = YES; // Get the message UIDs of all the emails in the mailbox CkoMessageSet *messageSet = [[CkoMessageSet alloc] init]; success = [imap QueryMbx: @"ALL" bUid: fetchUids msgSet: messageSet]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } CkoEmailBundle *bundle = [[CkoEmailBundle alloc] init]; BOOL headersOnly = YES; success = [imap FetchMsgSet: headersOnly msgSet: messageSet bundle: bundle]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // The UID of each fetched email header is available // in the ckx-imap-uid header field. CkoEmail *email = [[CkoEmail alloc] init]; CkoMessageSet *msgSet1 = [[CkoMessageSet alloc] init]; int i = 0; int szBundle = [bundle.MessageCount intValue]; while (i < szBundle) { [bundle EmailAt: [NSNumber numberWithInt: i] email: email]; // Build a message set containing one UID NSString *uidStr = [email GetHeaderField: @"ckx-imap-uid"]; [msgSet1 FromCompactString: uidStr]; // Move this message to some other folder. success = [imap MoveMessages: msgSet1 destFolder: @"someOtherFolder"]; if (success != YES) { NSLog(@"%@",imap.LastErrorText); // Exit the loop... i = szBundle; } i = i + 1; } // Disconnect from the IMAP server. success = [imap Disconnect]; |
