Going from NavigationController to TabBarController

So... I've got a ViewController that's being pushed onto a NavigationController. In interface builder I create a separate ViewController and Embed it into a TabBarController and it looks good in Interface Builder.

In my app, I'm trying to go from one of the ViewControllers in my NavigationView to the ViewController in the TabBarController. How would I do this the correct way? I can't just push the view onto the NavigationController, because the tab bar at the bottom won't show up.

Any help would be greatly appreciate.

I believe you're operating with the UINavigationController and UITabBarController in a backwards order to recommended best-practice.

Unless something has changed in the last year or two (which may have happened) the UINavigationController should never have a UITabBarController pushed onto it. If you are using a UITabBarController in your app, it should be the window.rootViewController, and the navigation controller being member of the UITabBarController's viewControllers array.

I'm trying to go from one of the ViewControllers in my NavigationView to the ViewController in the TabBarController. How would I do this the correct way?

In that structure, you'd assign your destination view controller as another element of the viewControllers array. Then, in my style, I'd send a NSNotification something like "LaunchOtherViewController" from your first view controller, and thus you have no need for the first view controller to know about the tab bar controller or second view controller. Then have some class that knows about the second view controller receive that notification, and update the selectedIndex of the UITabBarController to that of the second, destination view controller.

Hope that makes sense.

You need to push the TabBarController onto the view. You may need to set the selected view controller of the tab bar, but it's important the tab bar controller be actually pushed onto the navigation stack (or presented modally).
