iphone - タブバーボタンでuiactionsheetをタップした後にセグエを呼び出す方法

Question

タブバーボタンにアクションシートを表示した後、セグエを呼び出す方法を知りたいと思います。

appdelegateがそれを行うのに適した場所でない場合、私はアプリデリゲートでこれらすべてを行いました。これらのコード行をどこに追加しますか？

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

    NSInteger choice = 1; // --> index of the view controller that should "act as button"
    if (viewController == [tabBarController.viewControllers objectAtIndex:choice])

        { 
            UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:nil 
                                                               delegate:self
                                                      cancelButtonTitle:@"Cancel" 
                                                 destructiveButtonTitle:Nil 
                                                      otherButtonTitles:@"000", @"Car Accident",@"Home",@"Property", nil];
            sheet.tag = 0;
            sheet.title=@"test";
            NSLog(@"tab tab");
                [sheet showInView:self.window];
                return NO;

    }


    NSLog(@"YES YES");
    return YES;
}


- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
     if(actionSheet.tag == 0)
    {

            if (buttonIndex == 0)
            {
                UIDevice *device = [UIDevice currentDevice];

                if ([[device model] isEqualToString:@"iPhone"])
                {
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt:000"]];

                } else
                {
                    UIAlertView *Notpermitted=[[UIAlertView alloc] initWithTitle:@"Alert" message:@"Your device doesn't support this feature." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    [Notpermitted show];
                }


            }
            else if (buttonIndex == 1)
            {
              NSLog(@"Car Accident");
                //tried to call a segue here.

            }
            else if (buttonIndex == 2)
            {

               NSLog(@"YES YES"); 
            }
            else if (buttonIndex == 3)
            {
               NSLog(@"YES YES"); 

            }
        }
}
