How do I connect UITabBar items from a UITabBar (not a UITabBarController) to different views in the IB?

问题

I’ve created a StoryBoard project and added a UITabBar to my first view and a few UITabBar items on it. I’m using a UITabBar and not a UITabBarController because the UITabBar needs to be scrollable vertically so it is inside a UIScrollView. I want to connect the UITabBar items to different ViewControllers. How do I do that inside the Interface builder?

With UITabBarController it’s just a Ctrl+drag like everything else in the IB, but for some reason the UITabBar acts differently. I’m aware of all the delegation methods I need to implement, but for now I’m only interested on how to connect the UITabBar items to the views.

回答1:

What you're probably after is UITabBarController.

You generally don't want to manage a UITabBar manually.

If you're using storyboards, you can drag out a UITabBarController and then Ctrl-drag from it to other view controllers in the storyboard to link them to the viewControllers property.

Try:

firstViewController.tabBarItem = firstItem;

回答3:

From UITabBar item ctr+drag to your next ViewController (select style push, modal).
Give you UITabbarItem tags.
Import UITabBarDelegate to your Controller.

Add following delegate method

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
    if (item.tag==0) {
        [self performSegueWithIdentifier:@"Favorite" sender:nil];
    }
    else if (item.tag==1)
    {
       [self performSegueWithIdentifier:@"Item" sender:nil];
    }
}

Give identifier for each segue.

you can get my demo from following link

but problem is that tabbar will not appear on next ViewController
