        [self.tweetSheet setInitialText:@"Some message."];
        [self.navigationController presentModalViewController:self.tweetSheet animated:YES];
    // Called when the tweet dialog has been closed
    self.tweetSheet.completionHandler = ^(TWTweetComposeViewControllerResult result)
    {
        NSString * msg;
        if (result == TWTweetComposeViewControllerResultCancelled)
        {
                msg = @"Tweet compostion was canceled.";
        }
        else if (result == TWTweetComposeViewControllerResultDone)
        {
            NSLog(@"result %d",result);
                msg = @"Tweet composition completed.";
        }

         UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Tweet Status" message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alertView show];
        // Show alert to see how things went...
        [self.tweetSheet dismissModalViewControllerAnimated:YES];

        // Dismiss the controller
       };
}

你不能添加一个布尔值吗？ repeated = FALSE，并在第一条消息出现时将其切换为TRUE。然后在完成处理程序块中验证

    else if (result == TWTweetComposeViewControllerResultDone && repeated != TRUE) {            

        NSLog(@"result %d",result);

        msg = @"Tweet composition completed.";

}
