objective-c - 在 Swift 中发送 Mailcore2 普通邮件

Question

我最近将 MailCore2 合并到我的 Objective-C 项目中，并且运行良好。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将以下工作 Objective-C 代码转换为 Swift 代码的文档(Google 搜索、libmailcore.com、github):

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!");
    }
}];

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

Answer 1

这是我的做法:

Step 1)导入mailcore2，我用的是cocoapods

pod 'mailcore2-ios'

步骤 2) 将 mailcore2 添加到您的桥接 header :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!")
    }
}
