IOS safe area planning guides for custom tabBar

Question

I have an application based on a custom tabBar controller, and now, since we have a secure area layout, I want to change my application to fully use the iPhone X screen.

So, I want to fix the tabBar problem, which currently does not address the safe area.

I went through most of the solutions that people post, but they are mostly for UIViewController.

My current tabBar is as follows

I use RDVTabBarfor this, and this tab bar is an instance UIView, and I do not use a storyboard or xib, everything is done programmatically.

Current code to fix the problem

if (@available(iOS 11.0, *)) {
    UILayoutGuide *safe = self.view.safeAreaLayoutGuide;
    self.tabBar.translatesAutoresizingMaskIntoConstraints = NO;

    [NSLayoutConstraint activateConstraints:@[[safe.trailingAnchor constraintEqualToAnchor:self.tabBar.trailingAnchor],
                                              [self.tabBar.leadingAnchor constraintEqualToAnchor:safe.leadingAnchor],
                                              [safe.bottomAnchor constraintEqualToAnchor:self.tabBar.bottomAnchor]]];

    [self.tabBar addConstraint:[NSLayoutConstraint constraintWithItem:self.tabBar
                                                      attribute:NSLayoutAttributeHeight
                                                      relatedBy:NSLayoutRelationEqual
                                                         toItem:nil
                                                      attribute: NSLayoutAttributeNotAnAttribute
                                                     multiplier:1
                                                       constant:45]];

}

But that doesn’t change anything

, ,

CGRect frame = self.tabBar.frame;
frame.origin.y = frame.origin.y - 34;
frame.size.height = frame.size.height + 34;
self.tabBar.frame = frame;

, , ; .

, , tabBar?
