从xCode发送数据库时出错

Question

我想从我的iphone应用程序发送附加到邮件的sqlite数据库，我收到电子邮件但不是数据库文件，对我的语法抱歉，我来自西班牙，这是我的代码。

-(IBAction)mandar:(id)sender 
{ 
    MFMailComposeViewController *composer=[[MFMailComposeViewController alloc]init]; 
    [composer setMailComposeDelegate:self]; 
    if ([MFMailComposeViewController canSendMail]) 
    { 
     [composer setToRecipients:[NSArray arrayWithObjects:@"Introducir direccion",nil]]; 
     [composer setSubject:@"Base de datos"]; 
     [composer setMessageBody:@"Mensage" isHTML:YES]; 
     [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 

     NSString *documentsDirectory = [paths objectAtIndex:0]; 

     NSString *file = [documentsDirectory stringByAppendingPathComponent:@"capturas.sqlite"]; 

     NSData *data=[NSData dataWithContentsOfFile:file]; 

     [composer addAttachmentData:data mimeType:@"application/sqlite" 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]; 
    } 
}

我认为你应该使用：

应用程序/ x-sqlite3的，而不是为mime类型

编辑应用程序/ SQLite的：这解决了它，并发送文件：

-(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]; 

从您的代码评论这些：

// NSArray * paths = NSSearchPathForDirectoriesInDomains （NSDocumentDirectory，NSUserDomainMask，YES）;

// NSString * documentsDirectory = [paths objectAtIndex：0];

// NSString * file = [documentsDirectory stringByAppendingPathComponent：@“capturas.sqlite”];

// NSData * data = [NSData dataWithContentsOfFile：file];

并用以下

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]; 
} 

}
