CSV not attaching to in app email?

Question

So I have had this problem for sometime and just cant get it working! I have been building a survey app that users simply enter information in and its saved to a csv file. Im no

Answer 1

So after many sleepless nights and a lot of trying different ways I finally found the way that works with a friend (see code below)

 NSString *docsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
    NSData *attachment = [NSData dataWithContentsOfFile:[docsDirectory stringByAppendingPathComponent:@"results.csv"]];

    MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
    mailer.mailComposeDelegate = self;
    [mailer setToRecipients:@[@"gpsflighttrial@gcap.eu"]];
    [mailer setSubject:self.subject.text];
    [mailer setMessageBody:self.message.text isHTML:NO];
    [mailer addAttachmentData:attachment mimeType:@"application/csv" fileName:@"results.csv"];
    [self presentModalViewController:mailer animated:YES];

Just in case anyone has this problem in the future.
