附加sqlite的Xcode的郵件

Question

我要瘋了這個代碼，它應該是工作，但是當我收到的郵件有沒有附加的文件，這裏是我的代碼：

-(IBAction)mandar:(id)sender 
{ 
    MFMailComposeViewController *composer=[[MFMailComposeViewController alloc]init]; 
    [composer setMailComposeDelegate:self]; 
    if ([MFMailComposeViewController canSendMail]) 
    { 
     [composer setToRecipients:[NSArray arrayWithObjects:@"tuperroensalsa@hotmail.com",nil]]; 
     [composer setSubject:@"Base de datos"]; 
     [composer setMessageBody:@"Mensage" isHTML:NO]; 
     [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
      NSArray *searchPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     NSString *documentPath = [searchPaths objectAtIndex:0]; 
     NSString *path = [[NSString alloc] initWithFormat:@"%@/capturas.sqlite",documentPath]; 

     NSString *Newpath = [[NSString alloc] initWithFormat:@"%@/newData.sqlite",documentPath]; 
     [[NSFileManager defaultManager] copyItemAtPath:path toPath:Newpath error:nil]; 
     NSData *data = [NSData dataWithContentsOfFile:Newpath]; 
     [composer addAttachmentData:data mimeType:@"application/x-sqlite3" fileName:@"capturas.sqlite"]; 

     [self presentModalViewController:composer animated:YES]; 
    } 
    else { 
     UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Error" message:@"No se a podido mandar el mensage" delegate:self cancelButtonTitle:@"dismis" otherButtonTitles:nil, nil]; 
     [alert show]; 
    } 
} 

的路徑是確定和數據庫中有數據，當我撰寫郵件時，我也會看到該文件，但沒有任何郵件到達我的郵件。我想這個問題是在這裏

[composer addAttachmentData:data mimeType:@"application/x-sqlite3" fileName:@"capturas.sqlite"]; 

，但不知道爲什麼它不工作，THX的幫助

我在已經更新了答案：Error sending database from xCode但似乎你沒有檢查它，反正這裏我們再次：

// NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
// NSString *documentsDirectory = [paths objectAtIndex:0]; 
// NSString *file = [documentsDirectory stringByAppendingPathComponent:@"capturas.sqlite"]; 
// NSData *data=[NSData dataWithContentsOfFile:file]; 

：

-(IBAction)mandar:(id)sender { 

MFMailComposeViewController *composer=[[MFMailComposeViewController alloc]init]; 
[composer setMailComposeDelegate:self]; 
if ([MFMailComposeViewController canSendMail]) 
{ 
    [composer setToRecipients:[NSArray arrayWithObjects:@"EMAIL Address here",nil]]; 
    [composer setSubject:@"Base de datos"]; 
    [composer setMessageBody:@"Mensage" isHTML:YES]; 
    [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 

從您的代碼，這些評論

而且隨着[錯誤從xcode的發送數據庫]下面

NSString *path = [[NSBundle mainBundle] pathForResource:@"database name without extension" ofType:@"sqlite"]; 
    NSData *myData = [NSData dataWithContentsOfFile:path]; 

    [composer addAttachmentData:myData mimeType:@"application/x-sqlite3" fileName:path]; 

    [self presentModalViewController:composer animated:YES]; 
} 
else { 
    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Error" message:@"No se a podido mandar el mensage" delegate:self cancelButtonTitle:@"dismis" otherButtonTitles:nil, nil]; 
    [alert show]; 
} 

}
