objective c - Envío de correos electrónicos simples de Mailcore2 en Swift

objective-c api

Question

Recientemente incorporé MailCore2 en mi proyecto Objective-C, y funcionó perfectamente. Ahora, estoy en proceso de transición del código dentro de la aplicación a Swift. He importado con éxito la API de MailCore2 en mi proyecto rápido, pero no veo documentación (búsqueda de Google, libmailcore.com, github) sobre cómo convertir el siguiente código Objective-C en código Swift:

MCOSMTPSession *smtpSession = [[MCOSMTPSession alloc] init];
smtpSession.hostname = @"smtp.gmail.com";
smtpSession.port = 465;
smtpSession.username = @"[email protected]";
smtpSession.password = @"password";
smtpSession.authType = MCOAuthTypeSASLPlain;
smtpSession.connectionType = MCOConnectionTypeTLS;

MCOMessageBuilder *builder = [[MCOMessageBuilder alloc] init];
MCOAddress *from = [MCOAddress addressWithDisplayName:@"Matt R"
                                              mailbox:@"[email protected]"];
MCOAddress *to = [MCOAddress addressWithDisplayName:nil 
                                            mailbox:@"[email protected]"];
[[builder header] setFrom:from];
[[builder header] setTo:@[to]];
[[builder header] setSubject:@"My message"];
[builder setHTMLBody:@"This is a test message!"];
NSData * rfc822Data = [builder data];

MCOSMTPSendOperation *sendOperation = 
   [smtpSession sendOperationWithData:rfc822Data];
[sendOperation start:^(NSError *error) {
    if(error) {
        NSLog(@"Error sending email: %@", error);
    } else {
        NSLog(@"Successfully sent email!");
    }
}];

¿Alguien sabe cómo enviar correctamente un correo electrónico en Swift usando esta API? Gracias de antemano a todos los que responden.

Answer 1

Así es como lo hice:

Paso 1) Importar mailcore2, estoy usando cocoapods

pod ''mailcore2-ios''

Paso 2) Agregue mailcore2 a su encabezado de puente: Project-Bridging-Header.h

#import <MailCore/MailCore.h>

Paso 3) Traduce rápido

var smtpSession = MCOSMTPSession()
smtpSession.hostname = "smtp.gmail.com"
smtpSession.username = "[email protected]"
smtpSession.password = "xxxxxxxxxxxxxxxx"
smtpSession.port = 465
smtpSession.authType = MCOAuthType.SASLPlain
smtpSession.connectionType = MCOConnectionType.TLS
smtpSession.connectionLogger = {(connectionID, type, data) in
    if data != nil {
        if let string = NSString(data: data, encoding: NSUTF8StringEncoding){
            NSLog("Connectionlogger: /(string)")
        }
    }
}

var builder = MCOMessageBuilder()
builder.header.to = [MCOAddress(displayName: "Rool", mailbox: "[email protected]")]
builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "[email protected]")
builder.header.subject = "My message"
builder.htmlBody = "Yo Rool, this is a test message!"

let rfc822Data = builder.data()
let sendOperation = smtpSession.sendOperationWithData(rfc822Data)
sendOperation.start { (error) -> Void in
    if (error != nil) {
        NSLog("Error sending email: /(error)")
    } else {
        NSLog("Successfully sent email!")
    }
}

Para enviar una imagen como archivo adjunto en poco tiempo solo agregue:

    var dataImage: NSData?
    dataImage = UIImageJPEGRepresentation(image, 0.6)!
    var attachment = MCOAttachment()
    attachment.mimeType =  "image/jpg"
    attachment.filename = "image.jpg"
    attachment.data = dataImage
    builder.addAttachment(attachment)

Answer 3

Para Swift 3 solo copie esto

    let smtpSession = MCOSMTPSession()
    smtpSession.hostname = "smtp.gmail.com"
    smtpSession.username = "[email protected]"
    smtpSession.password = "xxxxxxx"
    smtpSession.port = 465
    smtpSession.authType = MCOAuthType.saslPlain
    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: "Rool", mailbox: "[email protected]")]
    builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "[email protected]")
    builder.header.subject = "My message"
    builder.htmlBody = "Yo Rool, this is a test message!"

    let rfc822Data = builder.data()
    let sendOperation = smtpSession.sendOperation(with: rfc822Data!)
    sendOperation?.start { (error) -> Void in
        if (error != nil) {
            NSLog("Error sending email: /(error)")
        } else {
            NSLog("Successfully sent email!")
        }
    }
