次のIBActionを使用して、いくつかの単純な受信データで構成されるCSVファイルを電子メールに添付していますが、電子メールコンポーザービューを開くと、本文セクションに灰色のファイルが表示され、実際にメッセージを送信します。メッセージは添付ファイルなしで送信されます。

これが私のコードです：

    - (IBAction)actionEmailComposer {
    NSLog(@"Receipts Count: %d", [receipts count]);
    //Create CSV File
    NSMutableString *csvString = [[NSMutableString alloc] init];
    [csvString appendString:@"Date,Business,Category,Paid By,Note, Number,Currency, Amount"];

    for (int i = 0; i < [receipts count]; i++){

        [csvString appendString: [[receipts objectAtIndex:i] receiptDate]];
        [csvString appendString: [[receipts objectAtIndex:i] business]];
        [csvString appendString: [[receipts objectAtIndex:i] category]];
        [csvString appendString: [[receipts objectAtIndex:i] paidBy]];
        [csvString appendString: [[receipts objectAtIndex:i] note]];
        [csvString appendString: [[receipts objectAtIndex:i] number]];
        [csvString appendString: [[receipts objectAtIndex:i] currency]];
        [csvString appendString: [[receipts objectAtIndex:i] amount]];

    }

    [csvString writeToFile:@"test.csv" atomically:YES encoding:NSUTF8StringEncoding error:NULL];

    if ([MFMailComposeViewController canSendMail]) {

        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
//        NSString *recipient = [defaults objectForKey:@"reportsEmail"];
        NSString *recipient = @"testemail@live.com";
        NSArray *recipients = [NSArray arrayWithObjects:recipient, nil];

        MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
        mailViewController.mailComposeDelegate = self;
        [mailViewController setSubject:@"CSV Export"];
        [mailViewController setToRecipients:recipients];
        [mailViewController setMessageBody:@"" isHTML:NO];
        mailViewController.navigationBar.tintColor = [UIColor blackColor];
        NSData *myData = [NSData dataWithContentsOfFile:@"test.csv"];

        [mailViewController addAttachmentData:myData 
                                     mimeType:@"text/csv" 
                                     fileName:@"test"];

        [self presentModalViewController:mailViewController animated:YES];

    }
    //Display alert to the user
    else {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Can't Send Mail"
                                                            message:@"Device is unable to send email in its current state." 
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK" 
                                                  otherButtonTitles:nil];

        [alertView show];
    }

}

csvString出力：

Date、Business、Category、Paid By、Note、Number、Currency、Amount "July 17、2012"、 "tho"、 "Category 1"、 "Cheque"、 "lunch"、 "726269"、 "GBP"、 "100.00 「」

したがって、既存のデータがありますが、正しく添付されていないようですが、ここで何が起こっているのかを誰かが説明できますか？

ありがとう、

ジャック

このコードを試してください

            arr_email=[[NSMutableArray alloc] initWithArray:[objDatabase lookupAllForSQL:@"select * from password"]];


    NSString *mystr=@"";
    NSString *str_type;
    NSString *str_name;
    NSString *str_user;
    NSString *str_pwd;
    NSString *str_url;
    NSString *str_descr;
    NSString *csvstr;

    csvstr=[NSString stringWithFormat:@"Account Type,Account Name,UserName/Card No,Password/Pin No, URL/Other Info,Description"];

    for (int i=0; i<[arr_email count]; i++) {
        NSMutableDictionary *dict = [arr_email objectAtIndex:i];

        str_type=[NSString stringWithFormat:@"%@",[dict objectForKey:@"AccountType"]];
        str_name=[NSString stringWithFormat:@"%@",[dict objectForKey:@"AccountName"]];
        str_user=[NSString stringWithFormat:@"%@",[dict objectForKey:@"UserName"]];
        str_pwd=[NSString stringWithFormat:@"%@",[dict objectForKey:@"Password"]];
        str_url=[NSString stringWithFormat:@"%@",[dict objectForKey:@"Url"]];
        str_descr=[NSString stringWithFormat:@"%@",[dict objectForKey:@"Description"]];

         mystr=[NSString stringWithFormat:@"%@ \n %@,%@,%@,%@,%@,%@",mystr,str_type,str_name,str_user,str_pwd,str_url,str_descr];

    }
    csvstr=[NSString stringWithFormat:@"%@ \n %@",csvstr,mystr];   
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docDir = [paths objectAtIndex:0];

    NSString *filename = [docDir stringByAppendingPathComponent:[NSString stringWithFormat:@"My Private Closet.csv"]];
    NSError *error = NULL;
    BOOL written = [csvstr writeToFile:filename atomically:YES encoding:NSUTF8StringEncoding error:&error];
    if (!written)
    NSLog(@"write failed, error=%@", error);

直感に反しますが、ファイルを添付するときのファイル名には拡張子が含まれていません。したがって、「test.csv」というファイル名で：

[mailViewController addAttachmentData:myData 
                             mimeType:@"text/csv" 
                             fileName:@"test"];
