(Objective-C) Delete All IMAP EmailDemonstrates two ways to delete all email in a mailbox on an IMAP server. Note: This example requires Chilkat v11.0.0 or greater.
#import <CkoImap.h> #import <CkoMessageSet.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]; // Turn on session logging: imap.KeepSessionLog = YES; // 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.RubyMail"]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Get the complete set of Uids for email in the selected mailbox. CkoMessageSet *messageSet = [[CkoMessageSet alloc] init]; success = [imap QueryMbx: @"ALL" bUid: YES msgSet: messageSet]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Set the Deleted flag for each message. // (ExpungeAndClose must be called to finalize the delete.) success = [imap SetFlags: messageSet flagName: @"Deleted" value: [NSNumber numberWithInt: 1]]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Alternatively, the Deleted flag may be set for each UID // individiually, but this is less efficient: int i = 0; int n = [messageSet.Count intValue]; while (i < n) { success = [imap SetFlag: [messageSet GetId: [NSNumber numberWithInt: i]] bUid: messageSet.HasUids flagName: @"Deleted" value: [NSNumber numberWithInt: 1]]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } i = i + 1; } // Expunge and close the mailbox. success = [imap ExpungeAndClose]; if (success == NO) { NSLog(@"%@",imap.LastErrorText); return; } // Display the session log. NSLog(@"%@",imap.SessionLog); // Disconnect from the IMAP server. success = [imap Disconnect]; |
