Question

In my navigation stack, I have 2 viewcontrollers, which were pushed to the navigation stack. Over that I have a PresentModalViewController as rootviewcontroller and I push 2 more viewcontrollers over it. So the navigation stack will be like

ViewController

ViewController

PresentModalViewController as rootviewcontroller

ViewController

ViewController

From the topmost viewcontroller, on a button click, I would like to move to the bottommost viewcontroller. The viewcontrollers in between should be popped or dismissed. How is it possible.
I have tried dismissModalViewControllerAnimated: and popToRootViewControllerAnimated: without any success.

Used delegates to solve this problem.

Class A.h
@protocol MyDelegateClass
- (void)didLoadHomeView; 


Class B.h
@interface MyViewController : UIViewController<MyHomeViewDelegate>

Class B.m
- (void)didLoadHomeView
{
    [self.navigationController popToRootViewControllerAnimated:YES];
}

Class C.h
@interface MyCurrentViewController : UIViewController
{
    id <MyLoadHomeDelegate> homeDelegate; 
}
    @property (nonatomic,assign) id <MyLoadHomeDelegate>   homeDelegate;

Class C.m
-(IBAction) OnHome:(id)sender{
    [self dismissModalViewControllerAnimated:NO];
    if (self.homeDelegate) {
        [homeDelegate didLoadHomeView];
    }

}

The ModalViewController, which is the current RootViewController is dismissed in the OnHome:(id)sender method in MyCurrentVIewController class. After dismissing the ModalViewController, I popped to the current rootviewcontroller in the navigation stack, which is the home view(firstViewController). The above code works perfectly in my case.
