Obtener archivo de texto del directorio del documento iPad

Question

Todos, en mi requisito necesitan enviar un correo con un archivo de texto adjunto, que está en el directorio de documentos, aquí puedo obtener la ruta del archivo que está en el directorio de documentos, ¿cómo conecto el archivo desde mi iPad para enviarlo?

Aquí está el código que he intentado

MFMailComposeViewController *picker=[[MFMailComposeViewController alloc]init];
picker.mailComposeDelegate=self;

if ([MFMailComposeViewController canSendMail]){
    // Create and show composer
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    NSLog(@"directry path %@",paths);
    NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:@"Logs/log-858743.txt"];

    NSLog(@"directry full path %@",fullPath);
    NSData *data = [NSData dataWithContentsOfFile: fullPath];
    NSLog(@"Data value %@",data);

    BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:fullPath];
    if (fileExists) {
        NSLog(@"file is there");
    }else{
        NSLog(@"file is not there");
    }

    [picker setSubject:@"Backup"];
    [picker addAttachmentData:data mimeType:@"text/rtf" fileName:@"log.txt"];
    [picker setMessageBody:@"testing." isHTML:NO];
    [self presentModalViewController:picker animated:YES];
    [picker release];    }
else{
    // Show some error message here
}

Here a sample, try this

MFMailComposeViewController *mViewController = [[MFMailComposeViewController alloc] init];
mViewController.mailComposeDelegate = self;

//Imposto l'oggetto
[mViewController setSubject:@"Invio Copia Commissione"];

//Preparo l' A: Devo spezzare gli indirizzi E-mail
NSArray *toRecipients = [NSArray arrayWithArray:[Globals.AEmail componentsSeparatedByString:@";"]];
[mViewController setToRecipients:toRecipients];


//Preparo il Cc: Devo spezzare gli indirizzi E-mail
if ([Config.EmailAgg length] != 0) {
    NSArray *CcRecipients = [NSArray arrayWithArray:[Config.EmailAgg componentsSeparatedByString:@";"]];
    [mViewController setCcRecipients:CcRecipients];
}

//Setto il corpo dell'E-mail
[mViewController setMessageBody:Globals.TestoEmail isHTML:NO];


//A questo punto visto che ho fatto 30 salvo il testo anche come file allegato dell'E-mail
[Globals.TestoEmail writeToFile:[NSString stringWithFormat:@"%@/CopiaCommissione.txt", Globals.DocumentsPath] atomically:TRUE encoding:NSUTF8StringEncoding error:nil];
NSData *Allegato = [NSData dataWithContentsOfFile:[NSString stringWithFormat:@"%@/CopiaCommissione.txt", Globals.DocumentsPath]];
[mViewController addAttachmentData:Allegato mimeType:@"text/plain" fileName:@"CopiaCommissione.txt"];


[self presentModalViewController:mViewController animated:YES];
[mViewController release];

try to change mimeType in your code like this

[picker addAttachmentData:data mimeType:@"text/plain" fileName:@"log.txt"];
