ios - 如何处理 iOS 6 中的重复推文错误

Question

我在其完成块中处理了推文取消和完成条件，它正在工作，当我发送重复推文时，它显示重复推文错误消息很好，但我的问题是在重复错误之后它显示推文已完成消息，所以我想停止推文完成消息如果出现重复的错误消息，请解决我的问题。这是我的工作代码。

self.tweetSheet = [[TWTweetComposeViewController alloc] init];
        [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？，并在出现第一条消息时将repeated = FALSE其切换到。TRUE然后在您的完成处理程序块中验证

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

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

        msg = @"Tweet composition completed.";

}
