How to render viewcontroller in this way using navigation controller

I have 3 view stacks namely MyHomeViewController, MySubViewController, MyReplyListViewController.

Now the MyHomeViewController is the root view. and w开发者_如何学Gohen i give back from MySubViewController it takes me to MyHomeViewController.as like and when i give back from MyReplyListViewController it takes me to MySubViewController using navigation controller

So, MyHomeViewController -> MySubViewController -> MyReplyListViewController

Now what i want is , when user received a new mail in the app.

When user launching the app and if he has received a new reply, i want to show the MyReplyListViewController first, from there when i give back it has to take me to MySubViewController. from there when i give back it has to take me to MyHomeViewController

MyReplyListViewController -> MySubViewController -> MyHomeViewController

This has to happen only once when he has received a new reply.otherwise it has to behave asusaul.

I am trying to accomplish this but no luck

Thanks for your time and support.

Try by using the UINaviationController viewControllers property and setViewControllers method,

@property(nonatomic, copy) NSArray *viewControllers;
- (void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated;

UPDATED:

For the below controllers.

MyReplyListViewController -> MySubViewController -> MyHomeViewController

You need to create and array of viewControllers in the reverse order shown above.

NSArray* myControllerArray = [NSArray arrayWithObjects:rootViewController, subViewController, replyViewController, nil];

set it as new stack of navigation.

[myNavigationController setViewControllers:myControllerArray animated:NO];

Now go directly to your MyReplyListViewController.

 [myNavigationController popToViewController:replyViewController animated:YES]
