Question

I have a UITabBarController with 4 views/tabs. Each view is a UINavigationController.

How can I popToRootViewController on one of these UINavigationControllers then switch tabs and push a viewController onto another UINavigationController using animation throughout?

So the sequence would be:

At start we are in Tab 1’s view which is a UINavigationController. A View has been pushed onto it beyond its root ViewController.

-Tab 1
   - UINavigationController1
      - RootViewController1
      - SomeViewController1 [We are here]

-Tab 2
   - UINavigationController2
      - RootViewController2

A button is tapped in SomeViewController1 that causes the following:

1. UINavigationController1 pops to its root view controller (with animation)
2. UITabBarController switches tab to Tab2
3. SomeViewController2 is pushed onto UINavigationController2 (with animation)

So the view looks like this:

-Tab 1
   - UINavigationController1
      - RootViewController1

-Tab 2
   - UINavigationController2
      - RootViewController2
      - SomeViewController2 [We are here]

Answer 1

int tabYouWantToSelect=2;
BOOL isNavigation=YES;
[[self.tabBarController selectedViewController].navigationController popToRootViewControllerAnimated:YES];

//if any controller is presented as a model view then
//[[self.tabBarController selectedViewController] dismissModalViewControllerAnimated:YES];

[self.tabBarController setSelectedIndex:tabYouWantToSelect];

//the newly pushed view controller's viewWillAppear
-(void)viewWillAppear:(BOOL)animated {
        if(isNavigation){
            [self.navigationController pushViewController:objAddLocation animated:YES];                
         }
}
