我正在尝试从我的 iphone 应用程序发送附加到邮件的 sqlite 数据库，我收到了电子邮件，但没有收到数据库文件，对不起我的语法，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：

application/x-sqlite3 而不是 mimeType 的 application/sqlite

编辑：这解决了它并发送了文件：

-(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];

从您的代码中评论了这些：

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

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

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

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

并替换为以下内容

    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];
}

}
