如何在ios 6中处理重复的推文错误

Question

我处理推文取消和完成条件在其完成块它正在工作,当我发送重复推文它显示重复推文错误消息确定没问题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已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)

                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
       };
}

不能添加布尔值吗？repeated = FALSE，并将其切换到TRUE第一条消息出现时。然后在您的完成处理程序块中只需验证

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

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

        msg = @"Tweet composition completed.";

}
