UIAlertView按钮到另一个ViewController

Question

I have two buttons for my UIAlertView . One of them goes back to TableViewController while another one have to go to another ViewController . The button that goes to the TableViewController can work. But the button that goes to the ViewController is showing me a blank view when I click the button.

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
    QuizTableViewController *quizTable = [self.storyboard instantiateViewControllerWithIdentifier:@"quizTable"];

    UINavigationController *quizController = [[UINavigationController alloc] initWithRootViewController:quizTable];
    [quizController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];

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

if (buttonIndex == 1)
{
    QuizAnsViewController *quizAns = [[QuizAnsViewController alloc] initWithNibName:nil bundle:nil]; 

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

}

The second part of the code is for the button to go another ViewController .

Anybody can help please? Thank you.

Answer 1

It seems you are using Story board so this might work

if (buttonIndex == 1){

   QuizAnsViewController *quizAns = [self.storyboard instantiateViewControllerWithIdentifier:@"Identifier_of_that_view_controller"]; 
   [self presentViewController:quizAns animated:YES completion:nil];
}

Answer 2

you use NavigationController than I think this code is Solve your problem. You can Try.

if (buttonIndex == 1)
{

        QuizAnsViewController * quizAns = [[[QuizAnsViewController alloc] initWithNibName:@"QuizAnsViewController" bundle:nil] autorelease];

    [self.navigationController quizAns animated:YES];

}
