Attaching .txt to MFMailComposeViewController
提问by Alex
I have a .txt file stored in Documents Folder and I want to send it by MFMailComposeViewController with next code in the body of -sendEmailmethod:
我有一个 .txt 文件存储在文档文件夹中，我想通过 MFMailComposeViewController 发送它，并在-sendEmail方法主体中使用下一个代码：
NSData *txtData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"dataBase" ofType:@"txt"]];
[mail addAttachmentData:txtData mimeType:@"text/plain" fileName:[NSString stringWithFormat:@"dataBase.txt"]];
When Mail composer appears I can see attachment in the mail body but I receive this mail without attachment. Maybe it is wrong MIME-type for .txt attachment or something wrong with this code?
当邮件编辑器出现时，我可以在邮件正文中看到附件，但我收到的这封邮件没有附件。也许 .txt 附件的 MIME 类型错误或此代码有问题？
Thanks
谢谢

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"];
Hope it helps.
希望能帮助到你。

In Swift 3, you can send mail with attachment like this
在 Swift 3 中，您可以像这样发送带有附件的邮件
@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(["[email protected]"])
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)
}
}
And then dismiss the composer controller on a result
然后在结果上关闭作曲家控制器
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
Make sure to subscribe to this delegate
确保订阅此委托
MFMailComposeViewControllerDelegate
