iPhone 的 smtp 客户端库

任何人都知道在 iphone 应用程序中使用的 Objective-C smtp 库。

我使用skpsmtpmessagehttp://code.google.com/p/skpsmtpmessage/ http://code.google.com/p/skpsmtpmessage/但当发送邮件到 gmail 时，它会将邮件正文作为附件发送。

thanks.

尝试使用https://github.com/MailCore/mailcore2 https://github.com/MailCore/mailcore2。它是异步的，支持大多数邮件协议。

看一下发送邮件的例子：

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

 MCOMessageBuilder *builder = [[MCOMessageBuilder alloc] init];
 MCOAddress *from = [MCOAddress addressWithDisplayName:@"Matt R"
                                      mailbox:@"[email protected] /cdn-cgi/l/email-protection"];
 MCOAddress *to = [MCOAddress addressWithDisplayName:nil 
                                    mailbox:@"[email protected] /cdn-cgi/l/email-protection"];
 [[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!");
   }
}];
