tabbar is not displaying in secondview controller

Question

I am new in iOS world.I am creating one tab-bar sample app.

There is one button in first view-controller when i click this button it goes to to second view-controller.In second view-controller i use one gridview and i left 100 space at bottom.

now in second view-controller i have to add one tab bar so i go to Editor->Embedin->Tabbar controller and run application but i do not see tab bar here.I also try to use tab bar controller on object library but same issue i found.

Why tab bar is not displaying in second view-controller.Any suggestion ?

button click event :-

SecondVC *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"SecondVC"];

[self.navigationController pushViewController:vc animated:YES];

Thanks .

SecondVC *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"SecondVC"]; [self.navigationController pushViewController:vc animated:YES]; — arpit, Jul 01 '16 at 10:13
I guess, You are calling directly the second viewcontroller. That's why it is loading the second view controller. — Puvanarajan, Jul 01 '16 at 10:18

@Proton Actually it's my project requirement when i click one button in first view controller and then in second view controller have grid view with tab bar. Any suggestion — arpit, Jul 01 '16 at 10:34
From 1st view controller, you should `present` to 2nd view controller. In 2nd VC, you can add new tabbar — Proton, Jul 01 '16 at 10:38

If you have the SecondVC embedded in a TabBarVC you need to present the TBVC instead of the SecondVC in order for the Tab Bar to actually appear.

So instead of doing:

SecondVC *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"SecondVC"];

[self.navigationController pushViewController:vc animated:YES];

you need to do:

TabBarVC *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"TabBarVC"];

[self.navigationController pushViewController:vc animated:YES];

This will add to the navigation stack the Tab Bar View Controller.

This might be the implementation you are looking for

I have one more issue after this. After click on button it goes to tab bar now but when i press back button the application crash and show me this error:- "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't add self as subview' " if i check it on google and change animation yes to no so it did not crash:- [self.navigationController pushViewController:vc animated:NO]; but when i click on first time back button it goes to again tabbar controller ie. embeded in second vc if i press second time back button now they go to first vc. any suggestion ? – arpit Jul 02 '16 at 06:49

Button to viewcontroller SecondVC set segue identifer name as Pass

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{if ([[segue identifier] isEqualToString:@"Pass"])
{
SecondVC* vc = [[SecondVC alloc] init];

vc = (SecondVC ) [[(UINavigationController)[[self.tabBarController viewControllers] objectAtIndex:0] viewControllers] objectAtIndex:0];

}
}
