Question

I know there are a multitude of questions regarding putting a navigation controller into a tabbar controller, but I want to change my navigation project to a tabbar project. I’m just not sure what exactly I need to change because I feel like I have to mess with some code and IB.

In code:

Is all I need to do is replace the navigationController with a tabBarController in my appDelegate

In IB:

Drag a tabBarController into my Objects and then do I drag my entire navigationController object into the tabBarController or just the RootViewController that is inside the navigationController?

Thanks for any advice on this. Normally, I would just give it a try but I feel like I could mess too much up.

Its an entirely new framework now as you want to shift from a UINavigationController to a UITabBarController. Just keep your view controllers as it is – you do not need to delete them.

1. Set the TabBarController as your rootViewController.

2. Use either the IB or code for creating them. If you use the IB, then open up a tabbarcontroller, and for each tabBarItem, assign the class to the different view controllers you had created. If you are doing this by code, I would suggest that you create an array of view controllers and add them to the TabBar.

   NSArray* viewControllerss = [[NSArray alloc] initWithObjects: self, viewController1, viewController2, nil];
   
   NSLog(@"I am printing view controller array %@", viewControllerss);
   
   [self.tabBarController setViewControllers:viewControllerss animated:YES];
