在iphone sdk中用身体发送背景中的电子邮件

Question

我正在开发app，因为我想在后台发送电子邮件。 因为我使用了“SKPSMTP”库，但是当我收到邮件时，它没有正文，所以任何人都可以告诉我我的代码在哪里错了。 以下是点击按钮的代码..

- (void)sendMessageInBack:(id)anObject
{
    if(![self validateEmail:txt_email.text])
    {
        if([txt_email.text isEqualToString:@""] )
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Mandatory field" message:@"Please fill complete email" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
            [alert release];
        }
        else
        {
            if(self.interfaceOrientation==UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation==UIInterfaceOrientationLandscapeRight ) 
            {
                if(rotate)
                [btn_Send setImage:[UIImage imageNamed:@"send_button.png"] forState:UIControlStateNormal];
            }
            else if(self.interfaceOrientation==UIInterfaceOrientationPortrait || self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown )
            {
                if(rotate)
                [btn_Send setImage:[UIImage imageNamed:@"send button1.png"] forState:UIControlStateNormal];

            }
