How to add tabbar controller as child view to parent view?

Question

- (void)viewDidLoad 
{
    [super viewDidLoad];

    UITabBarController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"tabbar"];
    [self addChildViewController:controller];
    controller.view.frame = CGRectMake(0,0, 500, 500);
    [self.view addSubview:controller.view];
    [controller didMoveToParentViewController:self];
}

How can I add tabbar viewcontroller as child view to uiviewcontroller in objective-C?

Answer 1

As already mentioned your already doing it here [self.view addSubview:controller.view]

The autoresizing mask of the view of the tabbar controller assumes the full size of its superview.

If you set the frame when instantiating the tabbar controller, be sure to change the autoresizingMask property of the tabbar's view so that it doesn't have flexible width or flexible right margin.

Answer 2

You have created the frame for UITabBarController *controller as-

controller.view.frame = CGRectMake(500,500, 500, 500);

the x and y origin is 500 , it looks like that the tab bar controller is added but it's origin is outside the visible frame of the screen.

Answer 3

if let controller = self.storyboard?.instantiateViewController(withIdentifier: "TabController") as? TabController {
        addChildViewController(controller)
        controller.view.frame = contentView.bounds
        contentView.addSubview(controller.view)
        controller.didMove(toParentViewController: self)
    }

Here 'contentView' is the UIView positioned in ViewController
