'Tried to pop to a view controller that doesn't exist.'

Question

I am getting this error when I call my method dismissView. Here is the method stub:

-(IBAction)dismissView
{
    RootViewController *rootController = [[RootViewC         


        

Answer 1

The UINavigationController has a stack of ViewControllers which is stored in the viewControllers(NSArray) property. Enumerate to the required ViewController and pop to that ViewController.

Following code should solve the problem.

-(IBAction)dismissView
{
    NSArray *array = self.navigationController.viewControllers;
    for (id controller in array) {
        if ([controller isKindOfClass:[RootViewController class]]) {
            [self.navigationController popToViewController:controller animated:YES];

        }
    }
}
