更改标签栏控制器的导航栏背景色

Question

My UI is just from TabBarController A to TabBarController B, those two TabBarController with different child items. Now I want to change the TabBarController B's navigationbar backgroundColor, but any of those methods followed are not work.

tabBarViewControllerA.navigationController.navigationBar.backgroundColor = [UIColor yellowColor]; babBarViewControllerB.navigationController.navigationBar.backgroundColor = [UIColor yellowColor]; babBarViewControllerB.childViewControllers.firstObject.navigationController.navigationBar.backgroundColor = [UIColor yellowColor];

Also, from the debug->view debugging->capture view hierarchy, I can see the navigationbar backgroundcolor has changed, but the finial color is not changes. Please give me some ideas about the problem.
