问题

I have check this in iOS 12 it's working fine. Issue is when I am going to search and push to second VC it working fine. when I back and again push to second VC then UITableview goes under the NavigationBar. Normal push working fine only issue when search active and push second time.

I have try this below solution but none of this are working for me.

1. UnderTopBar
2. forKeyPath:"hidesShadow"
3. edgesForExtendedLayout
4. automaticallyAdjustsScrollViewInsets
5. extendedLayoutIncludesOpaqueBars
6. self.view layout too.

IF any one have same issue then please try this solution..

It's working for me. I hope it's working for you too.

Objective-C

-(void)viewWillDisappear:(BOOL)animated{
    if (@available(iOS 13.0, *)) {
        [self.navigationController.view setNeedsLayout]; 
        [self.navigationController.view layoutIfNeeded];
    }
}

Swift

func viewWillDisappear(_ animated: Bool) {
    if (@available(iOS 13.0, *)) {
         self.navigationController?.view.setNeedsLayout()     
         self.navigationController?.view.layoutIfNeeded()
    }
}

If this is not working then please check in OS Version 13.1.3. I think it's working.
