Go to rootView from another view when a button tapped

Question

I am using to change tabs (rootView) programatically by using this code:

NSInteger tabitem = tabBarController.selectedIndex;
[[tabBarController.viewControllers objectAtIndex:tabitem] popToRootViewControllerAnimated:YES];

But when I want to use a button to change the tab from a view, I cannot display the rootView. I am using this code but it does not show the rootView:

self.tabBarController.selectedIndex = 3;

This is the solution:

int index = 3;
self.tabBarController.selectedIndex = index;
[self.tabBarController.viewControllers[index] popToRootViewControllerAnimated:NO];
