title: TWTweetComposeViewController deprecated in IOS6
body: <p>My code is working as expected just that I need to get rid of this warning message.
  TWTeetComposeViewController deprecated in IOS6. Any replacement for this built-in view controller in ios6?</p>
  
  <p>Here is my sample code.</p>
  
  <pre><code>if ([TWTweetComposeViewController canSendTweet]) {
      // Initialize Tweet Compose View Controller
      TWTweetComposeViewController *vc = [[TWTweetComposeViewController alloc] init];
      // Settin The Initial Text
      [vc setInitialText:@"This tweet was sent using the new Twitter framework available in iOS 5."];
      // Adding an Image
      UIImage *image = [UIImage imageNamed:@"sample.jpg"];
      [vc addImage:image];
      // Adding a URL
      NSURL *url = [NSURL URLWithString:@"http://mobile.tutsplus.com"];
      [vc addURL:url];
      // Setting a Completing Handler
      [vc setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
          [self dismissModalViewControllerAnimated:YES];
      }];
      // Display Tweet Compose View Controller Modally
      [self presentViewController:vc animated:YES completion:nil];
  } else {
      // Show Alert View When The Application Cannot Send Tweets
      NSString *message = @"The application cannot send a tweet at the moment. This is because it cannot reach Twitter or you don't have a Twitter account associated with this device.";
      UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops" message:message delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
      [alertView show];
  }
  </code></pre>
