ios - How to post on twitter by hiding SLComposeViewController *tweetSheettweet instance

Question

My app needs to support iOS 5.

I have my custom UI where user can enter tweet message and when he presses post button, It should post message twitter.

I have already written code for posting via SLComposeViewController *tweetSheet instance but in this case i cannot directly press send button presented by tweetSheet without presenting it by

[self presentViewController:tweetSheet animated:YES completion:nil];

Is it possible to bypass this presentation and set text message and post to twitter via my custom ui which has post button ??

  if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
    {
        SLComposeViewController *tweetSheet = [SLComposeViewController
                                               composeViewControllerForServiceType:SLServiceTypeTwitter];


        tweetSheet.completionHandler = ^(SLComposeViewControllerResult result) {
            switch(result) {
                    //  This means the user cancelled without sending the Tweet
                case SLComposeViewControllerResultCancelled:
                    NSLog(@"Tweet message was cancelled");
                    break;
                    //  This means the user hit 'Send'
                case SLComposeViewControllerResultDone:
                    NSLog(@"Done pressed successfully");
                    break;
            }

            //  dismiss the Tweet Sheet
            dispatch_async(dispatch_get_main_queue(), ^{
                [self dismissViewControllerAnimated:NO completion:^{
                    NSLog(@"Tweet Sheet has been dismissed.");
                }];
            });
        };

        [tweetSheet setInitialText:self.textViewPostedText.text];

        [self presentViewController:tweetSheet animated:YES completion:nil];
    }

How to give select option if user have multiple Twitter accounts ???

 - (IBAction)doneButtonClicked:(id)sender
  {
    ACAccountStore *account = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
    NSString *message = _textView.text;
    //hear before posting u can allow user to select the account
    NSArray *arrayOfAccons = [account accountsWithAccountType:accountType];
    for(ACAccount *acc in arrayOfAccons)
    {
       NSLog(@"%@",acc.username); //in this u can get all accounts user names provide some UI for user to select,such as UITableview 
    } 
in below 


 // Request access from the user to access their Twitter account
  [account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
  {
     if (granted == YES)
      {
         // Populate array with all available Twitter accounts
         NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
         if ([arrayOfAccounts count] > 0)
         {
             //use the first account available
             ACAccount *acct = [arrayOfAccounts objectAtIndex:0]; //hear this line replace with selected account. than post it :)

             //Build a twitter request
             TWRequest *postRequest = [[TWRequest alloc] initWithURL:

              //for iOS 6 use "https://api.twitter.com/1/statuses/update.json"
              //Post the request
              //u should get the response code 200 for successful post
             [postRequest setAccount:acct];

             //manage the response
             [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)

                 if(error)
                  {
                      //if there is an error while posting the tweet
                      UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"Error in posting" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

                      NSLog(@"Twitter response, HTTP response: %i", [urlResponse statusCode]);
                      UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"Successfully posted" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                      [alert show];
