(Swift) How to Download Messages in MessageSet One at a TimeIf a message set contains a huge number of emails, it's NOT a good idea to try to download all at once into an email bundle using a method such as FetchBundle. It's better to iterate over the messages in the set to download one by one. Note: This example requires Chilkat v11.0.0 or greater.
func chilkatTest() { var success: Bool = false // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. let imap = CkoImap()! // Connect using TLS. imap.ssl = true imap.port = 993 success = imap.connect("imap.example.com") if success == false { print("\(imap.lastErrorText!)") return } // Authenticate success = imap.login("email_account_login", password: "email_account_password") if success == false { print("\(imap.lastErrorText!)") return } // Select an IMAP mailbox success = imap.selectMailbox("Inbox") if success == false { print("\(imap.lastErrorText!)") return } // Search for messages and return a set of matching messages. // (This example will simply search for ALL messages.) var fetchUids: Bool = true let messageSet = CkoMessageSet()! success = imap.queryMbx("ALL", bUid: fetchUids, msgSet: messageSet) if success == false { print("\(imap.lastErrorText!)") return } print("Number of messages = \(messageSet.count.intValue)") let email = CkoEmail()! var i: Int = 0 while i < messageSet.count.intValue { success = imap.fetchEmail(false, msgId: messageSet.getId(i), bUid: fetchUids, email: email) if success == false { print("\(imap.lastErrorText!)") return } print("\(email.from!); \(email.subject!)") i = i + 1 } print("OK") } |
