iphone – 将sqlite附加到xcode邮件

发布时间：2020-12-14 18:05:52 所属栏目：百科来源：网络整理

导读：我对这段代码感到很疯狂,它应该可以工作,但是当我收到邮件时没有附加文件,这是我的代码： -(IBAction)mandar:(id)sender{ MFMailComposeViewController *composer=[[MFMailComposeViewController alloc]init]; [composer setMailComposeDelegate:self]; if (

我对这段代码感到很疯狂,它应该可以工作,但是当我收到邮件时没有附加文件,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:@"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];
    }
}

路径没问题,数据库中有数据,我在编写邮件时也看到了文件,但没有任何内容到达我的邮箱.我猜问题就在这里

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

但不知道为什么它不起作用,thx的帮助

解决方法

我已经更新了答案： Error sending database from xCode但似乎你没有检查它,无论如何这里它又是：

-(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];

从您的代码中评论这些：

//  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,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];
}

}
