弹出项目的第一个视图控制器

Question

I have a UINavigationController . I load a presentmodalviewcontroller over it. And I push 2 more view controllers over the presentmodalviewcontroller . If I need to move to my first view controller, what should be done?

Edit: I am also loading some UIView over the UIViewController on top of my stack. I have successfully removed that.

I have tried

 [self.navigationController popToRootViewControllerAnimated:YES];
 [self.navigationController dismissModalViewControllerAnimated:YES];  
 [self.navigationController popToViewController:[self.navigationController.viewControllers   objectAtIndex:0] animated:YES]; 

but still its not working

This is how I am adding each view controller

First viewcontroller

 FirstViewController *firstViewController = 
 [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];

 UINavigationController *navcontrol =[[UINavigationController alloc]initWithRootViewController:firstViewController];
 [self presentModalViewController:navcontrol animated:YES];
 [navcontrol release];

Second viewcontroller

SecondViewController *secondViewController = [[SecondViewController alloc]init] ;
[self.navigationController pushViewController: secondViewController animated:YES];
        [secondViewController release];

Third viewcontroller

ThirdViewController *thirdViewController = [[ThirdViewController alloc] init];
[self.navigationController pushViewController: thirdViewController animated:YES];
[thirdViewController release];

Ok. I got it.

    myAppDelegate *appDelegate = (myAppDelegate*)[UIApplication sharedApplication].delegate;

    [appDelegate.navigationController dismissModalViewControllerAnimated:YES];
