TabBar moving up whenever a ViewController is pushed in iPhone X

I've recently added support to iOS 11 on my app and this started happening. Basically, whenever a ViewController is added to the navigation stack the tab bar glitches out during the animation.

It only happens in iPhone X, and this is just a regular TabBarController. What's causing it?

A radar is open about this problem here.

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];

    // Disable tabBar shifts upward whenever a ViewController is pushed on iPhone X rdar://35098813
    BOOL isIPhoneX = ...
    if (isIPhoneX && UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation)) {
        [self.tabBar setFrame:CGRectMake(0, CGRectGetHeight(self.view.frame) - CGRectGetHeight(self.tabBar.frame), CGRectGetWidth(self.view.frame), CGRectGetHeight(self.tabBar.frame))];
    }
}

Original answer

I think this is a bug of iOS 11. You can remove that weird effect to put down this code to your subclass of UITabBarController.

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];
    BOOL isIPhoneX = ...
    if (isIPhoneX && UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation)) {
        [self.tabBar setFrame:CGRectMake(0, self.view.frame.size.height - 83, 375, 83)];
    }
}

The solution is weird, too. :)
