在 Swift 中发送 Mailcore2 普通电子邮件

Question

我最近将 MailCore2 合并到我的 Objective-C 项目中，它运行良好。现在，我正在将应用程序中的代码转换为 Swift。我已成功将 MailCore2 API 导入到我的 swift 项目中，但我没有看到有关如何打开将工作 Objective-C 代码转换为 Swift 代码：

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

MCOMessageBuilder *builder = [[MCOMessageBuilder alloc] init];
MCOAddress *from = [MCOAddress addressWithDisplayName:@"Matt R"
                                              mailbox:@"matt@gmail.com"];
MCOAddress *to = [MCOAddress addressWithDisplayName:nil 
                                            mailbox:@"hoa@gmail.com"];
[[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!");
    }
}];

有谁知道如何使用 API 在 Swift 中成功发送电子邮件？提前感谢所有回复的人。

Answer 1

我是这样做的：

步骤1)导入mailcore2，我用的是cocoapods

pod 'mailcore2-ios'

步骤 2) 将 mailcore2 添加到您的桥接头：Project-Bridging-Header.h

#import <MailCore/MailCore.h>

步骤 3) 转换为 swift

var smtpSession = MCOSMTPSession()
smtpSession.hostname = "smtp.gmail.com"
smtpSession.username = "matt@gmail.com"
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: "itsrool@gmail.com")]
builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "matt@gmail.com")
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!")
    }
}

要在 swift 中将图片作为附件发送，只需添加：

    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

对于Swift 3 只需复制此

    let smtpSession = MCOSMTPSession()
    smtpSession.hostname = "smtp.gmail.com"
    smtpSession.username = "sanipcr7@gmail.com"
    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: "sanipcr7@gmail.com")]
    builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "matt@gmail.com")
    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!")
        }
    }

Answer 4

我会在答案下方的评论中添加这个，但有这么多。

接受的答案中的步骤特别有效，特别是使用 link 到您的 google 帐户的特殊应用程序密码。

但是@RoolPaap 使用的桥接头与我使用的不同。我用了 #include "Mailcore.h"

我关注了这个youtube video

#ifndef MyProjectName_Bridging_Header_h
#define MyProjectName_Bridging_Header_h

#include "Mailcore.h"

#endif /* MyProjectName_Bridging_Header_h */
