Question

Let me explain. I have multiple UIViewControllers. On my MainPageController, I have 3 UIViews. Let’s enumerate it this way: the first UIView is called LoginView, the second is called HomeView and the other one is called RegView. Now in HomeView, there are multiple buttons that will lead to other UIViewControllers. For example, one button will lead to StoreController. Now if I am inside StoreController and I want to go back to MainPageController, I simply call:

[self dismissModalViewControllerAnimated:YES completion:nil]

This will send me back to the HomeView.

That is good. However, inside the StoreController, there are buttons which will supposedly direct me to LoginView or RegView, whichever button was tapped. The problem is when the method [self dismissModalViewControllerAnimated:YES completion:nil], it only take me back to HomeView, no matter which button I pressed.

So how will I display the right UIView once the dismissModalViewControllerAnimated is called?

EDIT:

This is how I show the UIViews:

-(void)viewDidLoad
{
  //Initialize the views here...
}

-(void)showViewByTag:(NSInteger)tag
{
   if (tag == 1)
   {
     [self.view addSubview:loginView];
   }
   else if (tag == 2)
   {
     [self.view addSubview:homeView];
   }
   else
   {
     [self.view addSubview:regView];
   }
}

Now I call the method showViewByTag: somewhere in my code to display the views.

What you could try and do is following: before calling [self dismissModalViewControllerAnimated:YES completion:nil] (and thus go back to your home view), change the view currently displayed in your MainPageController:

[(MainPageController*)self.presentingViewController showViewByTag:desiredViewTag];
[self dismissModalViewControllerAnimated:YES...];

If you are worried at the cast and you foresee that self.presentingViewController might be not of MainPageController type on some occasions, then you can check explicitly for its type:

if ([self.presentingViewController isKindOf:[MainPageController class]])
    [(MainPageController*)self.presentingViewController showViewByTag:desiredViewTag];
[self dismissModalViewControllerAnimated:YES...];

For this to compile, MainPageController.h must be imported in your modal controller class.
