Determine which tab select in tabbarcontroller

I've implemented the following in my app delegate and attempted to check the selected index. What I've found though is this value is the tab that it's on when a new tab is clicked, not the new tab. Is there a way to find which tab was selected?

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController
{
    int *i = tabBarController.selectedIndex;
}

Swift version:

func tabBarController(tabBarController: UITabBarController, shouldSelectViewController viewController: UIViewController) -> Bool {
    var shouldSelect = true
    if let viewControllers = tabBarController.viewControllers where viewControllers.indexOf(viewController) == lastIndex {
        shouldSelect = false
    }
    return shouldSelect
}

If I am not mistaken, you can get the index of the selected tab with

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController
    NSUInteger selectedIndex = [tabBarController.viewControllers indexOfObject:viewController];
    // ...
    return YES or NO;
}

You want to use the tabBarController:didSelectViewController: delegate method. That is called after the tab is selected.

And your int *i should actually be int i or better yet, NSUInteger i.
