Change Container View Content with Tabs in iOS

Question

I\'m trying to make a form that spans three tabs. You can see in the screenshot below where the tabs will be. When the user taps a tab, the Container View should update and show

Answer 1

have a member variable to hold the viewController:

UIViewController *selectedViewController;

now in the IBActions, switch that AND the view. e.g.

- (IBAction)tab1:(id)sender {
     UIViewController *viewController1 = [self.storyboard instantiateViewControllerWithIdentifier:@"vc1"];

     _container.view = viewController1.view;
     selectedViewController = viewController1;
}

to fire view did appear and stuff call removeChildViewController, didMoveToParent, addChildViewController, didMoveToParent
