tabBarController:shouldSelectViewController: not being called when delegate is set

around this issue Ok, found the solution. I had some old code in my RootViewController that set up this controller as the delegate. No delegate methods were implemented on the RootViewController, so it appeared as if nothing was happening. Because the RootViewController is set as delegate AFTER MyAppDelegate, the delegate was actually set to the RootViewController.
So the lesson is double-check your code to make sure some other object isn't also being set as the delegate.

help you fix your problem I found a simpler solution to my problem. Inside of ViewControllerTwo, I just create an instance of ViewControllerOne and pass it that data I need. Then I change the tabBarController index to ViewControllerOne.
For example:
code :
// A method inside of ViewControllerTwo
ViewController *viewcontrollerOne = [ViewcontrollerOne alloc] init];
[viewcontrollerOne setStringData:str];
[viewcontrollerOne release];
self.tabBarController.selectedIndex = 0;

help you fix your problem The viewController getting from the story board is a tab bar controller.
code :
  UIStoryboard *secondStoryBoard = [UIStoryboard storyboardWithName:@"MainFunction" bundle:nil];
  UITabBarViewController *theInitialViewController = [secondStoryBoard instantiateInitialViewController];

    [theInitialViewController setSelectedIndex:2];
    [self.window makeKeyAndVisible];
