Answer 1

i'll provide another solution for this bug(seems apple made).

and the solution is not to forbid the tabbar move up , but to make the black area will not show when tabbar move up

the core thing is add a subview to your viewcontroller as it deepest subview and this subview's frame is the window size.so when the tabbar moves up , this subview will shown insteadof black area

if (@available(iOS 11.0, *)) {
    UIView* bgView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds];
    bgView.autoresizingMask = UIViewAutoresizingNone;
    bgView.backgroundColor = UIColorFromRGB(0xefeff4);
    [self.view addSubview:bgView];

}

the convenience of this method is you will not have to subclass tabbar or overwrite navigationcontroller's push method
