发送委托的MFMessageComposeViewController短信(MFMessageComposeViewController sms sent delegate)

 我在我的应用程序MFMessageComposeViewController中实现了发送短信。 它运作良好，但我不知道是否可以知道消息实际发送的时间。 
 
-(void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients {

    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

    if([MFMessageComposeViewController canSendText]) {

      controller.body = bodyOfMessage;    
      controller.recipients = recipients;
      controller.messageComposeDelegate = self;
      [self presentModalViewController:controller animated:YES];

    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {

  [self dismissModalViewControllerAnimated:YES];

  if (result == MessageComposeResultCancelled) {

    NSLog(@"Message cancelled");

  } else if (result == MessageComposeResultSent) {

    NSLog(@"Message sent");
  }

}
 
 if（result == MessageComposeResultSent）仅对应于“发送”按钮，但如果消息已发送，则不会发出警告。 你知道是否有某种方式委派或知道短信是否被发送？ 
 
 非常感谢！ 

I implemented in my app MFMessageComposeViewController for send sms. It works well, but I do not know if it is possible to know when the message is actually sent.
 
-(void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients {

    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

    if([MFMessageComposeViewController canSendText]) {

      controller.body = bodyOfMessage;    
      controller.recipients = recipients;
      controller.messageComposeDelegate = self;
      [self presentModalViewController:controller animated:YES];

    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {

  [self dismissModalViewControllerAnimated:YES];

  if (result == MessageComposeResultCancelled) {

    NSLog(@"Message cancelled");

  } else if (result == MessageComposeResultSent) {

    NSLog(@"Message sent");
  }

}
 
if (result == MessageComposeResultSent) corresponds only to the button "send" but not really a warning if the message has been sent. Do you know if there is some way to delegate or know if the SMS was sent or not?
 
Thanks a lot!
