将.txt附加到MFMailComposeViewController

我有一个.txt文件存储在文档文件夹中，我想通过MFMailComposeViewController发送下一代码在-sendEmail方法的主体：

 NSData *txtData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"dataBase" ofType:@"txt"]]; [mail addAttachmentData:txtData mimeType:@"text/plain" fileName:[NSString stringWithFormat:@"dataBase.txt"]]; 

当邮件编辑器出现时，我可以在邮件正文中看到附件，但是我收到这封没有附件的邮件。 也许这是错误的.txt附件的MIMEtypes或此代码的错误？

谢谢

Answer 1

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *txtFilePath = [documentsDirectory stringByAppendingPathComponent:@"abc.txt"]; NSData *noteData = [NSData dataWithContentsOfFile:txtFilePath]; MFMailComposeViewController *_mailController = [[MFMailComposeViewController alloc] init]; [_mailController setSubject:[NSString stringWithFormat:@"ABC"]]; [_mailController setMessageBody:_messageBody isHTML:NO]; [_mailController setMailComposeDelegate:self]; [_mailController addAttachmentData:noteData mimeType:@"text/plain" fileName:@"abc.txt"]; 

希望能帮助到你。

在Swift 3中，你可以用这样的附件发送邮件

 @IBAction func emailLogs(_ sender: Any) { let allPaths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) let documentsDirectory = allPaths.first! let pathForLog = documentsDirectory.appending("/application.log") if MFMailComposeViewController.canSendMail() { let mail = MFMailComposeViewController() mail.mailComposeDelegate = self; mail.setToRecipients(["[e-mail]"]) mail.setSubject("Application Logs") mail.setMessageBody("Please see attached", isHTML: true) if let fileData = NSData(contentsOfFile: pathForLog) { mail.addAttachmentData(fileData as Data, mimeType: "text/txt", fileName: "application.log") } self.present(mail, animated: true, completion: nil) } } 

然后closurescomposer php控制器的结果

 func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { controller.dismiss(animated: true, completion: nil) }
