ios 使用 mailcore 发送电子邮件不起作用

Question

我正在尝试使用 MailCore 发送电子邮件，但未发送电子邮件。如果我做错了什么，请提出建议。发送电子邮件的代码如下:

-(void) sendMail{
     NSLog(@"entered");
    CTCoreMessage *testMsg = [[CTCoreMessage alloc] init];
    [testMsg setTo:[NSSet setWithObject:[CTCoreAddress addressWithName:@"recipients name" email:@"recipient@gmail.com"]]];
    [testMsg setFrom:[NSSet setWithObject:[CTCoreAddress addressWithName:@"sender name(me)" email:@"my_e_mail@google.com"]]];
    [testMsg setBody:@"This is a test message!"];
    [testMsg setSubject:@"This is a subject"];
    NSLog(@"Init values");
    NSError *error;
    BOOL success = [CTSMTPConnection sendMessage:testMsg
                                          server:@"smtp.gmail.com"
                                        username:@"my_e_mail"
                                        password:@"pwd"
                                            port:587
                                  connectionType:CTSMTPConnectionTypeStartTLS
                                         useAuth:YES
                                           error:&error];
    NSLog(@"Success is %c", success);
    if (!success) {
        // Present the error
        NSLog(@"Mail not sent");
    }
}

Here it's the working solution..!!

        let smtpSession = MCOSMTPSession()
            smtpSession.hostname = "smtp.gmail.com"
            smtpSession.username = "XXX@gmail.com"
            smtpSession.password = "xxxxxxx"
            smtpSession.port = 465 // Gmail port number
        smtpSession.authType = MCOAuthType.xoAuth2
            smtpSession.connectionType = MCOConnectionType.TLS
            smtpSession.connectionLogger = {(connectionID, type, data) in
                if data != nil {
                    if let string = NSString(data: data!, encoding: String.Encoding.utf8.rawValue){
                        NSLog("Connectionlogger: \(string)")
                    }
                }
            }

            let builder = MCOMessageBuilder()
        builder.header.to = [MCOAddress(displayName: "Vishnu", mailbox: senderEMail) as Any]
        builder.header.from = MCOAddress(displayName: SingletonClass.sharedInstance.userName, mailbox: SingletonClass.sharedInstance.userEmail)
        builder.header.subject = "MyMessage"
            builder.htmlBody = "Hey Buddy, this is a test message!"
        
            let rfc822Data = builder.data()
            let sendOperation = smtpSession.sendOperation(with: rfc822Data!)
            sendOperation?.start { (error) -> Void in
                if (error != nil) {
                    print("Error sending email: \(error?.localizedDescription)")
                    NSLog("Error sending email: \(error?.localizedDescription)")
                } else {
                    print("Successfully sent email!")
                    NSLog("Successfully sent email!")
                }
            }
