AutoLayout issue with TabBarController - ios

Question

I have encountered a very awkward autolayout issue. I have a Navigation controller, i have set its rootviewcontroller as tabbarview controller for some purpose. See Image bellow:
In above image you can see there are 6 viewcontroller connected with tabbarviewcontroller.
In 3rd 4th 5th and 6th viewcontroller a white view is added and autolayout as given below:
Now, after run when i select tab 3 or 4, the added view shows perfectly as i wanted and according to autolayout it should be show as it is showing. i.e given below:
Now when I select "more" then it showing a tableviewcontroller as it should be according to its default behaviour, is given below:
Here is the problem occurred, now if you select any item from the list and go to respected view controller, the white view added goes down from navigation bar. I don't understand why this happening. please see in the pic:
Whole day I had tried to fix this but nothing happens, some how got one solution but it was not what I needed here. i.e see Image below:
If uncheck "Under Top Bars" for that view controller then its works fine, but it affects the navigation bar, which I not wanted here. please see the image:
Can somebody here who had faced the similar kind of problem and found a perfect solution and I'm looking for help.
Note: No class have been taken in any view controller, all are in storyboard.
Thanks in advance.

Answer 2

Took a UiTbaBarControllerClass for my tabbarcontroller and in that that controller i set delegate self and follow my code, now its working as i wanted. very thanks to #KKRocks
Code:
#import "TabBarController.h"
#interface TabBarController ()<UITabBarControllerDelegate>
#end
#implementation TabBarController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.delegate = self;
}
#pragma mark UITabBarController Delegate
- (void)tabBarController:(UITabBarController *)tabBarController
didSelectViewController:(UIViewController *)viewController
{
NSLog(#"controller class: %#", NSStringFromClass([viewController class]));
NSLog(#"controller title: %#", viewController.title);
if ([viewController.title isEqual:#"More"]) {
[self.navigationController setNavigationBarHidden: YES animated: NO];
}
}
And in Swift:
class TabBarController: UITabBarController, UITabBarControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.delegate = self
}
// MARK: UITabBarController Delegate
func tabBarController(_ tabBarController: UITabBarController, didSelectViewController viewController: UIViewController) {
print("controller class: \(String(describing: viewController.self))")
print("controller title: \(String(describing: viewController.title))")
if viewController.title?.isEqual("More") {
navigationController?.setNavigationBarHidden(true, animated: false)
}
}
}
Now it working very fine. :)
