We've done exactly the same in our application. To hide the default TabBar, simply override the hidesBottomBarWhenPushedmethod in your parent view controller (or in every view controller in your App)
我们在我们的应用程序中做了完全相同的事情。要隐藏默认 TabBar，只需覆盖hidesBottomBarWhenPushed父视图控制器（或应用程序中的每个视图控制器）中的方法
#pragma mark - Overriden UIViewController methods
- (BOOL)hidesBottomBarWhenPushed {
return YES;
}
EDIT: This value can also be set from Storyboard:

I don't think there's an easy way to fix this because UITabbarViewControlleris probably your super view and all "inner" views' height = screenHeight - tabBarHeight - navBarHeight.
我认为没有一种简单的方法可以解决这个问题，因为UITabbarViewController可能是您的超级视图和所有“内部”视图的 height = screenHeight - tabBarHeight - navBarHeight。
Maybe you can try to resize your inner view controller manually but then I think you might have problems with Apple's AppStore submission process, because I think this violates general iOS user experience.
也许您可以尝试手动调整内部视图控制器的大小，但我认为您可能在 Apple 的 AppStore 提交过程中遇到问题，因为我认为这违反了一般的 iOS 用户体验。

And this is how you'd do the override (UIViewController) in Swift:
这就是您UIViewController在 Swift 中执行覆盖 ( ) 的方式：
override var hidesBottomBarWhenPushed: Bool {
get { return true }
set { super.hidesBottomBarWhenPushed = newValue }
}

My UITabBarControlleris housed within a container view. Checking "Hide Bottom Bar on Push" was not working for me. Instead I created a subclass of the tab bar controller and hid the tab bar programmatically.
MyUITabBarController位于容器视图中。检查“推送时隐藏底部栏”对我不起作用。相反，我创建了标签栏控制器的子类并以编程方式隐藏了标签栏。
class FooTabBar: UITabBarController {
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
self.tabBar.isHidden = true
}
}
